Correlating radio access network messages of aggressive mobile devices

ABSTRACT

Excessive signaling by devices against a radio access network (RAN) can be detected and mitigated. A security management component (SMC) can determine whether a total number of control signals received by a base station from devices satisfies a threshold total number of control signals indicative of excessive signaling. If so, SMC can identify a device associated with the base station based on analyzing communication conditions associated with the device. SMC can determine whether to classify the device as an excessive signaling device based on whether the number of control signals received from the device by the base station satisfies a threshold number of control signals indicative of excessive signaling. If so, SMC can determine the device is an excessive signaling device. In response, SMC can perform or facilitate performing a mitigation action to mitigate excessive signaling or can generate statistics relating to the excessive signaling.

DETAILED DESCRIPTION

Various aspects of the disclosed subject matter are now described withreference to the drawings, wherein like reference numerals are used torefer to like elements throughout. In the following description, forpurposes of explanation, numerous specific details are set forth inorder to provide a thorough understanding of one or more aspects. It maybe evident, however, that such aspect(s) may be practiced without thesespecific details. In other instances, well-known structures and devicesare shown in block diagram form in order to facilitate describing one ormore aspects.

Discussed herein are various aspects that relate to detecting andmitigating aggressive (e.g., excessive) signaling and/or maliciousevents, such as, for example, distributed denial of service (DDoS)attacks (also referred to herein as signaling storms), against acommunication network (e.g., wireless communication network) usingmachine learning techniques and algorithms, and, when aggressivesignaling and/or malicious event is detected, determining a desiredaction(s), which can include a mitigation action, to perform to mitigatethe aggressive signaling and/or malicious event, present an alertregarding the aggressive signaling and/or malicious event, and/or tolearn more information regarding the aggressive signaling and/ormalicious event. The disclosed subject matter can enhance detection andmitigation of aggressive signaling and/or malicious events against thecommunication network, enable critical communications and/or benigncommunications to be communicated via the communication network withoutdisruption, enhance the user experience with regard to communicationsvia the communication network, enhance security of the communicationnetwork, and enhance network efficiency of the communication network.

The various aspects described herein can relate to new radio, which canbe deployed as a standalone radio access technology or as anon-standalone radio access technology assisted by another radio accesstechnology, such as Long Term Evolution (LTE), for example. It should benoted that although various aspects and embodiments have been describedherein in the context of 5G, Universal Mobile Telecommunications System(UMTS), and/or Long Term Evolution (LTE), or other next generationnetworks, the disclosed aspects are not limited to 5G, a UMTSimplementation, and/or an LTE implementation as the techniques can alsobe applied in 2G, 3G, 4G, or LTE systems. For example, aspects orfeatures of the disclosed embodiments can be exploited in substantiallyany wireless communication technology. Such wireless communicationtechnologies can include UMTS, Code Division Multiple Access (CDMA),Wi-Fi, Worldwide Interoperability for Microwave Access (WiMAX), GeneralPacket Radio Service (GPRS), Enhanced GPRS, Third Generation PartnershipProject (3GPP), LTE, Third Generation Partnership Project 2 (3GPP2)Ultra Mobile Broadband (UMB), High Speed Packet Access (HSPA), EvolvedHigh Speed Packet Access (HSPA+), High-Speed Downlink Packet Access(HSDPA), High-Speed Uplink Packet Access (HSUPA), Zigbee, or anotherIEEE 802.XX technology. Additionally, substantially all aspectsdisclosed herein can be exploited in legacy telecommunicationtechnologies. Further, the various aspects can be utilized with anyRadio Access Technology (RAT) or multi-RAT system where the mobiledevice operates using multiple carriers (e.g., LTE Frequency DivisionDuplexing (FDD)/Time-Division Duplexing (TDD), Wideband Code DivisionMultiplexing Access (WCMDA)/HSPA, Global System for MobileCommunications (GSM)/GSM EDGE Radio Access Network (GERAN), Wi Fi,Wireless Local Area Network (WLAN), WiMax, CDMA2000, and so on).

As used herein, “5G” can also be referred to as New Radio (NR) access.Accordingly, systems, methods, and/or machine-readable storage media forreducing interference on reference signals from other co-channelreference signals, and improving the channel estimation performance forCSI estimation and data detection, in 5G systems, and other nextgeneration systems, can be desired. As used herein, one or more aspectsof a 5G network can comprise, but is not limited to, data rates ofseveral tens of megabits per second (Mbps) supported for tens ofthousands of users; at least one gigabit per second (Gbps) that can beoffered simultaneously to tens of users (e.g., tens of workers on thesame office floor); several hundreds of thousands of simultaneousconnections supported for massive sensor deployments; spectralefficiency that can be significantly enhanced compared to 4G;improvement in coverage relative to 4G; signaling efficiency that can beenhanced compared to 4G; and/or latency that can be significantlyreduced compared to LTE.

Multiple Input, Multiple Output (MIMO) technology can be employed incommunication networks, wherein MIMO technology can be an advancedantenna technique utilized to improve spectral efficiency and, thereby,boost overall system capacity. Spectral efficiency (also referred to asspectrum efficiency or bandwidth efficiency) refers to an informationrate that can be transmitted over a given bandwidth in a communicationsystem.

For MIMO, a notation (M×N) can be utilized to represent the MIMOconfiguration in terms of a number of transmit antennas (M) and a numberof receive antennas (N) on one end of the transmission system. Examplesof MIMO configurations used for various technologies can include: (2×1),(1×2), (2×2), (4×2), (8×2) and (2×4), (4×4), (8×4). The configurationsrepresented by (2×1) and (1×2) can be special cases of MIMO known astransmit and receive diversity.

In some cases, MIMO systems can significantly increase the data carryingcapacity of wireless communications systems. Further, MIMO can be usedfor achieving diversity gain, which refers to an increase insignal-to-interference ratio due to a diversity scheme and, thus, canrepresent how much the transmission power can be reduced when thediversity scheme is introduced, without a corresponding performanceloss. MIMO also can be used to achieve spatial multiplexing gain, whichcan be realized when a communications system is transmitting differentstreams of data from the same radio resource in separate spatialdimensions (e.g., data is sent/received over multiple channels, linkedto different pilot frequencies, over multiple antennas). Spatialmultiplexing gain can result in capacity gain without the need foradditional power or bandwidth. In addition, MIMO can be utilized torealize beamforming gain. Due to the benefits achieved, MIMO can be anintegral part of the third generation wireless system and the fourthgeneration wireless system. In addition, 5G systems also will employmassive MIMO systems (e.g., hundreds of antennas at the transmitter sideand receiver side). Typically, with a (N_(t), N_(r)), where N_(t)denotes the number of transmit antennas and N_(r) denotes the number ofreceive antennas, the peak data rate can multiply with a factor of N_(t)over single antenna systems in a rich scattering environment.

Communication devices can communicate information (e.g., voice and/ordata traffic) to other communication devices via a communicationnetwork, which can comprise a core network that can operate to enablewireless communication between communication devices. For example, awireless communication device (e.g., mobile, cell, or smart phone;electronic tablet or pad; computer; . . . ) can connect to andcommunicate with a wireless communication network (e.g., core network)to communicate with another communication device connected to thewireless communication network or to another communication network(e.g., Internet Protocol (IP)-based network, such as the Internet)associated with (e.g., communicatively connected to) the wirelesscommunication network.

Communication devices can operate and communicate via wireless orwireline communication connections (e.g., communication links orchannels) in a communication network to perform desired transfers ofdata (e.g., voice and/or data communications), utilize services, engagein transactions or other interactions, and/or perform other operations.In addition to wireless phones, electronic pads or tablets, andcomputers being used and connected to the communication network,increasingly Internet of Things (IoT) devices are being used andconnected to the communication network. The number of IoT devices beingemployed is expected to increase exponentially into the tens of billionsof IoT devices, which has been referred to as massive IoT. Massive IoTcan be one of the key service drivers for 5G and other next generationcommunication networks.

Many IoT devices can have security vulnerabilities, such as Zero Dayvulnerabilities, such as security holes in the software of the IoTdevices that can be unknown to the vendor and can be exploited bymalicious users (e.g., hackers or criminals). Malicious users canexploit such vulnerabilities in IoT devices, for example, to createbotnet armies by infecting IoT devices with stealthy malware (e.g., bysurreptitiously installing stealthy malware on IoT devices). Thissecurity threat can be expected to increase in magnitude due to the“massive” factor in massive IoT.

One of the main goals of these botnet armies of infected IoT devices canbe to disrupt communication services, including mission critical 5G andother next generation services, of a communication network by means ofDDoS attacks, which also are known as signaling storms. Since 5G andother next generation communication networks will facilitate massive IoTaccessing the 5G and other next generation radio access network (RAN),this can increase the risk of RAN resource (e.g., 5G or other nextgeneration RAN resource) overload by means of DDoS attacks disruptingservices, including mission critical 5G and other next generationservices, of the communication network.

Core networks (e.g., mobility network) today have no protection againstDDoS attacks originated from devices that are connected to the network.Currently, this is not expected to change with 5G networks. Yet, 5Gnetworks can be expected to support a significantly larger number ofdevices, including massive IoT. Therefore, the threat landscape posed byattacks originated by devices toward their network can be expected togrow significantly over the coming years.

By design, a RAN is not supposed to reveal subscriber identifiers ofcommunication devices. In part, subscriber identifiers are not revealedby the RAN because it is assumed that the radio interface can be moreexposed to eavesdropping, and antenna sites may be physically accessed.For this reason, temporal random identifiers can be used as a referenceto communication devices (e.g., mobile or wireless communicationdevices). This situation can pose a problem when trying to distinguishmisbehaving or malicious devices from benign devices at the RAN level.Distinguishing between malicious (or at least aggressive) and benigndevices can be desirable for mitigating DDoS attacks at the RAN. Notknowing which device is malicious (or at least aggressive) or benign canleave an undesired option of blocking both malicious (or aggressive) andbenign, which in itself can be a form of DDoS. Traditional mitigationmechanisms can be blind to the identity of a device, including maliciousor aggressive devices. Some traditional mitigation mechanisms can blockall communication devices, including benign (e.g., non-malicious)communication devices, associated with a base station, if a thresholdattach rate is breached. This can undesirably deny communicationservices to benign communication devices.

To that end, techniques for managing communication connections ofcommunication devices to a communication network (e.g., core network),including detecting and mitigating excessive signaling (e.g., aggressivesignaling) and/or malicious events (e.g., malicious attacks) bycommunication devices (e.g., aggressive or malicious communicationdevices) against a RAN, while allowing other communication devices(e.g., non-aggressive and/or non-malicious communication devices) toconnect and communicate via the RAN, are presented. This disclosedsubject matter can provide techniques that can protect a core networkfrom aggressive or malicious devices and can apply such protection inthe edge of the core network, which can thereby save resources of thecore network from being used unnecessarily and can preserve thoseresources for use in other parts of the core network.

The disclosed subject matter can comprise a security managementcomponent (SMC) that can employ a detector component that can detectexcessive signaling and/or malicious events by communication devicesassociated with base stations (e.g., base station or one or moreassociated cells) of one or more RANs. In some embodiments, the SMC canbe part of or associated with a RAN (e.g., the SMC can be part of a RANintelligent controller (RIC) of the RAN). The detector component candetermine whether a total number of control signals received by a basestation from communication devices associated with the base stationduring a defined time period satisfies (e.g., breaches, or meets orexceeds) a defined threshold total number of control signals that can beindicative of excessive signaling, based at least in part on the resultsof analyzing activity (e.g., communication of signals, such as controlsignals) associated with the base station and communication devices.Control signals can comprise, for example, an attach request signal torequest an attachment to the base station (e.g., an initial attachrequest or an update attach request), a connection request signal torequest a connection to the base station, a handover-related signalassociated with a handover of a communication device to or from the basestation, or another type of control signal.

In response to determining that the total number of control signalsreceived during the defined time period satisfies the defined thresholdtotal number of control signals, the detector component can determinethat there can be, or at least potentially can be, one or morecommunication devices that are engaging in excessive signaling againstthe base station. In further response, the detector component canidentify one or more communication devices associated with the basestation based at least in part on the results of analyzing informationrelating to respective communication conditions associated withrespective communication devices associated with (e.g., connected to)the base station. The detector component can determine that a set ofsignaling can be attributed to a certain communication device (e.g., anaggressive or excessive signaling, and/or malicious acting,communication device) by analyzing the signal characteristics associatedwith the communication device in relation to (e.g., in contrast to) thesignal characteristics of other communication devices. For instance, thedetector component can identify measurements of communication conditionsthat can identify (e.g., be a communication signature of) acommunication device, wherein, for example, multiple same or similarmeasurements of communication conditions can indicate that suchcommunication conditions are associated with the same communicationdevice. The communication conditions associated with a communicationdevice can comprise, for example, a received signal strength indicator(RSSI), a received signal received power (RSRP), a received signalreceived quality (RSRQ), a channel quality indicator (CQI), a signal tointerference and noise ratio (SINR), and/or a timing advance (TA)associated with the communication device. By identifying the respectivesignal characteristics (e.g., respective communication signatures) ofthe respective communication devices, the detector component cancorrelate signals or messages associated with different temporaryidentifiers and can attribute all of those signals or messages to asingle communication device (e.g., an aggressive or excessive signaling,and/or malicious acting, communication device), even though such signalsor messages are associated with different temporary identifiers.

In some embodiments, in addition to analyzing communication conditionsassociated with communication devices, the detector component cananalyze configuration parameters and/or other information associatedwith communication devices to facilitate identifying communicationdevices. The configuration parameters associated with a communicationdevice can comprise, for example, a quality of service class identifier(QCI), allocation and retention priority (ARP) parameter, a mobilitymanagement entity or access management function (MME/AMF) code, aMME/AMF group identifier, or a band frequency associated with thecommunication device.

The detector component can evaluate one or more communication devices(e.g., identified communication devices), and, for each communicationdevice, can determine whether to classify the communication device as anexcessive signaling device based at least in part on whether the numberof control signals received from the communication device by the basestation during the defined time period satisfies a defined thresholdnumber of control signals that can be indicative of excessive signalingby the communication device. If the detector component determines thatthe communication device satisfies the defined threshold number ofcontrol signals, the detector component can determine that thecommunication device is an excessive signaling device.

In some embodiments, in response to determining a communicationdevice(s) is an excessive signaling communication device(s), thedetector component can determine and generate a set of statisticsrelating to the excessive signaling and excessive signalingcommunication device(s). The detector component can present the set ofstatistics to another component of the SMC, a communication device, aninterface component (e.g., display screen, audio speakers, or otherinterface), and/or a user. In other embodiments, additionally oralternatively, in response to determining a communication device(s) isan excessive signaling communication device(s), the SMC can perform orfacilitate performing a mitigation action (e.g., blocking ordisconnecting an excessive signaling communication device from the basestation) to mitigate (e.g., eliminate or reduce) excessive signaling bythe communication device(s) identified as excessive signalingcommunication device(s).

These and other aspects and embodiments of the disclosed subject matterwill now be described with respect to the drawings. It is to beappreciated and understood that, while various aspects and embodimentsof the disclosed subject matter are described herein with regard to 5Gand other next generation communication networks, the techniques of thedisclosed subject matter described herein can be utilized (e.g., appliedto), in same or similar form, to 4G communication networks, and thedisclosed subject matter includes all such aspects and embodimentsrelating to implementation of the techniques of the disclosed subjectmatter to 4G communication networks.

Inaccordance with various embodiments, a network node can be, cancomprise, or can be associated with (e.g., communicatively connected to)a network device of the communication network 102.

At given times, one or more communication devices, such as, for example,communication device 104, communication device 106, and communicationdevice 108, can connect or attempt to connect to the communicationnetwork 102 to communicate with other communication devices associatedwith the communication network 102.

In some embodiments, more than a single antennaelement can be mapped to a single antenna port.

As disclosed, communication network 102 (e.g., the mobility core networkof the communication network 102) can comprise various networkcomponents or devices, which can include one or more RANs, such as, forexample, RAN 110, wherein each RAN can comprise or be associated with aset of base stations (e.g., access points (APs), such as base station112, that can serve communication devices located in respective coverageareas served by respective base stations in the mobility core network ofthe communication network 102. The respective base stations (e.g., basestation 112) can be associated with one or more sectors (not shown),wherein respective sectors can comprise one or more respective cells.The one or more cells can have respective coverage areas that can formthe coverage area covered by the one or more sectors. The respectivecommunication devices can be communicatively connected to thecommunication network 102 via respective wireless or wirelinecommunication connections with one or more of the respective cells.

In some embodiments, the one or more RANs (e.g., RAN 110) can be anopen-RAN (O-RAN) that can employ an open interface that can supportinteroperability of devices (e.g., network devices) from differententities (e.g., vendors). The O-RAN can build or establish wirelessconnections through virtualization. In certain embodiments, the O-RANcan utilize a common platform that can reduce reliance on proprietaryplatforms of service providers. The O-RAN also can employ standardizedinterfaces and application programming interfaces (APIs) to facilitateopen source implementation of the O-RAN.

The number of communication devices, particularly IoT devices, beingutilized is increasing at a significant rate and can be expected tocontinue to increase significantly into the future (e.g., increase totens of billions of devices). While in most instances, the communicationdevices (e.g., 104, 106, or 108) and associated users can be attemptingto connect to the RAN 110 for appropriate or benign reasons, in someinstances, aggressive and/or malicious actors can utilize communicationdevices to attempt to connect to the RAN 110 to disrupt (e.g., obstructor interrupt) services, such as mobility services, provided by thecommunication network 102, including the RAN 110. For example, maliciousactors can utilize communication devices (e.g., 104 or 106), such as IoTdevices, and exploit vulnerabilities of such devices (e.g., byinstalling malware on such communication devices) to initiate amalicious event, such as a DDoS attack, against the RAN 110 to overwhelmthe RAN 110 (e.g., base station 112 and/or RAN 110) and disrupt theservices provided by the RAN 110 and/or associated communication network102, including disrupting communication between communication devices(e.g., non-malicious acting communication devices) connected to orattempting to connect to the RAN 110 and/or associated communicationnetwork 102, as more fully described herein. The disclosed subjectmatter can determine (e.g., intelligently, automatically, and/ordynamically) determine when aggressive signaling and/or malicious eventsagainst the base station 112 and associated RAN 110 by certain (e.g.,aggressive, malicious, and/or malware infected) communication devices isoccurring (e.g., in real time or substantially in real time), as morefully described herein.

In some cases, there can be communication devices that are attempting toconnect to the RAN 110 to communicate benign messages and/or tocommunicate priority (e.g., high priority or critical) messages, via theRAN 110, to other communication devices associated with thecommunication network 102. If there is aggressive communication (e.g.,aggressive or excessive signaling) and/or a malicious event against theRAN 110, the aggressive communication and/or malicious event, if notmitigated, can disrupt services of the RAN 110 to prevent acommunication device attempting to connect and communicate benign orpriority message via the RAN 110, and/or, if all communication devicesattempting to connect to the RAN 110 during an aggressive communicationand/or malicious event were to be blocked from connecting, that canundesirably (e.g., negatively) impact the ability of benign (e.g.,non-aggressive or otherwise appropriately acting) communication devicesthat are attempting to connect to the RAN 110 to communicate benign orpriority messages from doing so. The disclosed subject matter candesirably (e.g., intelligently, automatically, and/or dynamically inreal time or substantially in real time) manage communicationconnections of communication devices to the RAN 110 (e.g., base station112 and/or RAN 110) and the communication network 102 (e.g., corenetwork), including detecting and mitigating excessive signaling (e.g.,aggressive signaling) and/or malicious events (e.g., malicious attacks)by communication devices (e.g., aggressive or malicious communicationdevices) against the RAN 110, while allowing other communication devices(e.g., non-aggressive and/or non-malicious communication devices) toconnect (or remain connected) and communicate via the base station 112and/or RAN 110.

To that end, in some embodiments, the RAN 110 can comprise a RANintelligent controller (RIC) 114 that can manage various functions andresources of or associated with the RAN 110 in real time orsubstantially close (e.g., near) to real time. In some embodiments, theRIC 114 can be part of an O-RAN (e.g., part of an overall architectureof the O-RAN). To facilitate securing the RAN 110 and communicationnetwork 102 overall from aggressive and/or malicious communicationdevices and/or malicious events (e.g., malicious attacks, such as DDoSattacks), the RIC 114 can comprise a security management component (SMC)116 that can detect and mitigate malicious events against the RAN 110and can manage connection of communication devices (e.g., 104, 106, or108) to the RAN 110 (e.g., manage connection of communication devicesduring aggressive signaling and/or malicious events), in accordance withdefined communication management criteria, which can comprise definednetwork security criteria. In some embodiments, the SMC 116 can employ asecurity application (e.g., malicious event and/or DDoS application) tofacilitate detecting and mitigating aggressive signaling and/ormalicious events against the RAN 110, and managing (e.g., controlling)connections of communication devices to the RAN 110. For example, thesecurity application can be a micro services application (e.g., xApp).In that regard, for instance, as part of the capabilities of the RIC114, micro services applications (e.g., xApps) can be written orimplemented on top of the RIC 114, and the SMC 116 can be or cancomprise the security application that can be a micro servicesapplication (e.g., xApp) that can be implemented on top of the RIC 114.

Communication devices (e.g., 104, 106, or 108) can communicate attachrequests or other types of communications (e.g., other types of signals,such as control signals) to the base station 112 and associated RAN 110to facilitate obtaining services or resources from the base station 112and associated RAN 110. For instance, a communication device (e.g.,communication device 104) can communicate an initial attach request tothe RAN 110 to request connection to the RAN 110, can communicateanother type of attach request (e.g., update request, such as anauthentication update request, a packet data network (PDN) gateway (PGW)update request, or other type of update request) to the RAN 110 torequest another type of service or resources from the RAN 110, cancommunicate a connection request signal to the RAN 110 to request aconnection to the base station (e.g., base station 112), can communicatea handover-related signal associated with a handover of a communicationdevice to or from the base station (e.g., base station 112), or cancommunicate another type of control signal to the base station (e.g.,base station 112) and RAN 110.

When communication devices (e.g., 104, 106, or 108) communicate controlsignals (e.g., attach requests or other types of control signals) to theRAN 110, the SMC 116 can receive information comprising or relating tosuch control signals. The RAN 110 and the SMC 116 can receive theinformation contained in the control signal (e.g., in an attach requestor other type of control signal) from the communication device (e.g.,communication device 104) and/or can receive other information (e.g.,other control signal-related information) from the communication deviceor network devices of the communication network 102. For instance, theRAN 110 can receive device identifier information (e.g., internationalmobile equipment identity (IMEI) number, international mobile subscriberidentity (IMSI) number, or other unique device identifier or serialnumber) that can identify the communication device, device locationinformation that can identify the location of the communication device,device type information that can identify the type of device thecommunication device is, priority information that can indicate orspecify a priority level associated with the communication device ormessage associated with the communication device, time data (e.g., timestamp data) that can indicate the time of the attach request or type ofcommunication or time(s) associated with another item(s) of attachrequest-related information, metadata associated with the attach requestand/or communication device, and/or other type of control signal-relatedinformation.

It is noted that, with regard to the device identifier information(e.g., IMEI, IMSI), while the RAN 110 can receive the device identifiers(e.g., IMEI, IMSI), the device identifiers are not revealed to the RAN110, because the network is not supposed to reveal device or subscriberidentifiers of communication devices in part because it is assumed thatthe radio interface can be more exposed to or compromised byeavesdropping, and antenna sites potentially can be physically accessed.For this reason, the RAN (e.g., RAN 110) and other network componentscan utilize temporal (e.g., temporary) random identifiers as a referenceto communication devices (e.g., mobile or wireless communicationdevices) and/or associated subscribers. Examples of temporal randomidentifiers can comprise cell radio network temporary identifier(C-RNTI) and temporary mobile subscriber identity (TMSI). A C-RNTI canbe a temporary unique identifier that can be used, instead of the IMEI,for example, for identifying the RRC connection and scheduling that canbe dedicated to a communication device. A TMSI can be a temporary uniqueidentifier that can be used, instead of the IMSI, to ensure or maintainthe privacy of the subscriber associated with a communication device.

In accordance with various embodiments, the SMC 116 can comprise adetector component 118 that can detect excessive signaling and/ormalicious events by communication devices associated with base stations(e.g., base station 112 or one or more associated cells) of one or moreRANs, such as RAN 110. Referring to FIG. 2 (along with FIG. 1 ), FIG. 2depicts a block diagram of the detector component 118, in accordancewith various aspects and embodiments of the disclosed subject matter.The detector component 118 can receive various types of information,including information relating to registration events associated withthe RAN 110 and information relating to control signals associated withcommunication devices, via a desired interface, such as, for example, anE2 interface 202. The various types of information can comprise, forexample, information relating to communication condition parameters andconfiguration parameters associated with communication devicesassociated with the RAN 110, information relating to control signals,and/or other desired information. The communication condition parametersassociated with a communication device (e.g., 104, 106, or 108) cancomprise, for example, a received signal strength indicator (RSSI), areceived signal received power (RSRP), a received signal receivedquality (RSRQ), a channel quality indicator (CQI), a signal tointerference and noise ratio (SINR), a timing advance (TA) associatedwith the communication device, and/or another desired measurement orvalue relating to communication conditions. The configuration parametersassociated with a communication device (e.g., 104, 106, or 108) cancomprise, for example, a quality of service class identifier (QCI),allocation and retention priority (ARP) parameter, a mobility managemententity or access management function (MME/AMF) code, a MME/AMF groupidentifier, a band frequency, or other desired configuration parameterassociated with the communication device.

In some embodiments, with regard to each control signal (e.g., attachrequest or other type of control signal or communication) received froma communication device (e.g., 104, 106, or 108), the detector component118 can analyze the information comprising or relating to such controlsignal. Based at least in part on the results of the analysis, thedetector component 118 can determine the type of control signal (e.g.,initial attach request, update attach request, authentication updaterequest, PGW update request, connection request, handover-relatedsignal, or other type of control signal), the time that such controlsignal was received or communicated, and/or other information relatingto the control signal or associated communication device.

The detector component 118, employing an aggressive device detectorcomponent 204, can determine whether a total number of control signalsreceived by the base station 112 (e.g., cell of the base station 112)from communication devices (e.g., 104, 106, or 108) associated with thebase station 112 during a defined time period satisfies (e.g., breaches,or meets or exceeds) a defined threshold total number of control signalsthat can be indicative of excessive signaling, based at least in part onthe results of analyzing activity (e.g., communication of signals, suchas control signals) associated with the base station 112 andcommunication devices (e.g., 104, 106, or 108). The defined thresholdtotal number of control signals that can be applicable at the time ofsuch analysis can be based at least in part on a number of factors,which can include the classification of the cell or associated basestation (e.g., base station 112), the type of control signal, whetherone type or more than one type of control signal is being considered,the length of the defined time period, the time of day, time of week,time or month, or time of year when such analysis is being performed,and/or other desired factors.

In certain embodiments, the detector component 118 can comprise a cellclassifier component 206 that can classify a cell (and/or associatedbase station (e.g., base station 112)) based at least in part on anumber of factors, such as, for example, the activity level associatedwith a cell, location of the cell, terrain and/or geography of the cellsite of the cell, and/or other desired factors, as more fully describedherein. In some embodiments, the detector component 118 (e.g., employinga machine learning component) can train and/or refine the cellclassifier component 206, using machine learning techniques andalgorithms, to enable the cell classifier component 206 to moredesirably (e.g., accurately, suitably, and/or efficiently) classifycells and/or associated base stations, such as more fully describedherein. For instance, the cell classifier component 206, using themachine learning techniques and algorithms, can determine and build aprofile for each cell (and/or associated base station (e.g., basestation 112)) of the communication network 102, wherein the profile cancomprise information relating to various parameters, such as, forexample, volume of connectivity and mobility events, signal power,signal quality, and behavior associated with the cell during variousdifferent times of the day, the week, the month, the year, and/or withregard to special events (e.g., holidays, sporting events, entertainmentevents, or other special events). These parameters can vary fordifferent cells, for example, based at least in part on whether a cellsite of a cell is located in a metropolitan area or a rural area, theterrain and/or geography of the cell site of the cell, and/or otherfactors.

For instance, a first cell or base station can be in a busy metropolitanarea, a second cell or base station can be located in a relatively ruraland less busy area, a third cell or base station can be located in anarea where there are various significant obstructions (e.g., hills,mountains, or tall buildings) that can impact the operation of the thirdcell or base station. The cell classifier component 206, using themachine learning techniques and algorithms, can analyze (e.g., perform amachine learning analysis on) the characteristics of the respectivecells or base stations, and, based on such analysis, can classify therespective cells or base stations and determine respective definedthreshold total number of control signals or respective sets of definedthreshold total number of control signals that can be used for therespective cells or base stations.

For example, with regard to a first cell or base station, which has afirst classification, the cell classifier component 206 can determineand the aggressive device detector component 204 can apply a firstdefined threshold total number of control signals or first set ofdefined threshold total number of control signals that can have arelatively high number(s) due in part to the first cell or base stationbeing located in a relatively busy area with regard to wirelesscommunication activity. With regard to a second cell or base station,which has a second classification, the cell classifier component 206 candetermine and the aggressive device detector component 204 can apply asecond defined threshold total number of control signals or second setof defined threshold total number of control signals that can have arelatively lower number(s) than that of the first cell or base stationdue in part to the second cell or base station being located in arelatively less busy area with regard to wireless communicationactivity.

As another example, with regard to a particular cell or associated basestation (e.g., base station 112), and based on the classification ofsuch cell or associated base station, the cell classifier component 206can determine a first defined threshold total number of control signalsthat can be applicable to the particular cell or base station during afirst time period of the day (or week or month or year) due to therelatively higher level of wireless communication activity (e.g.,relatively busy) associated with that first time period. The cellclassifier component 206 also can determine a second defined thresholdtotal number of control signals that can be applicable to the particularcell or associated base station during a second time period of the day(or week or month or year) due to the relatively lower level of wirelesscommunication activity (e.g., not too busy) associated with that secondtime period, wherein the first defined threshold total number can behigher than the second defined threshold total number due in part to therelatively higher level of wireless communication activity associatedwith the first time period and the relatively lower level of wirelesscommunication activity associated with the second time period.

As still another example, with regard to a cell (or associated basestation (e.g., base station 112)), as part of the classification of thecell, the cell classifier component 206 can determine defined thresholdtotal numbers of control signals based at least in part on the type ofcontrol signal (e.g., a first defined threshold total number of controlsignals can be applied to a first type of control signal, and a seconddefined threshold total number of control signals can be applied to asecond type of control signal). As yet another example, the cellclassifier component 206 can determine a defined threshold total numbersof control signals that can be applied with regard to all types ofcontrol signals and respective defined threshold total numbers ofcontrol signals that can be applied with regard to respective types ofcontrol signals, with regard to a cell (or associated base station(e.g., base station 112)), as part of the classification of the cell.

In response to the aggressive device detector component 204 determiningthat the total number of control signals received by the base station112 (or associated cell) from the communication devices (e.g., 104, 106,and/or 108) during the defined time period does not satisfy (e.g., doesnot breach, or does not meet or exceed) the applicable defined thresholdtotal number of control signals, the aggressive device detectorcomponent 204 can determine that there is not an indication of excessivesignaling by the communication devices. The detector component 118 cancontinue to monitor the communication activity associated with the basestation 112 (or cell) and perform additional analyses to facilitatedetecting excessive signaling and/or malicious events, if any occur.

If, instead, the aggressive device detector component 204 determinesthat the total number of control signals received by the base station112 (or associated cell) from the communication devices (e.g., 104, 106,and/or 108) during the defined time period satisfies the applicabledefined threshold total number of control signals, the aggressive devicedetector component 204 can determine that there can be, or at leastpotentially can be, one or more communication devices that are engagingin excessive signaling against the base station 112 (or associatedcell). In further response, the aggressive device detector component 204can identify one or more communication devices (e.g., 104, 106, and/or108) associated with the base station 112 based at least in part on theresults of analyzing information relating to respective communicationconditions (e.g., respective communication condition, signaling, ormessaging characteristics) associated with respective communicationdevices associated with (e.g., connected to) the base station 112. Theaggressive device detector component 204 can utilize the respectivecommunication conditions of the respective communication devices (e.g.,104, 106, and/or 108) to identify (at least indirectly identify) thecommunication devices based at least in part on their respectivecommunication signatures (e.g., communication condition signatures),since the device and subscriber identifiers (e.g., IMEI or IMSI)associated with the communication devices are not made available to thedetector component 118 or other components of or associated with thecommunication network 102. For example, the aggressive device detectorcomponent 204 can determine that a set of signaling (e.g., a set orgroup of control signals or other type of signals or messages) can beattributed to a certain communication device (e.g., an aggressive orexcessive signaling, and/or malicious acting, communication device)based at least in part on the results of analyzing the signalcharacteristics (e.g., communication condition signature) associatedwith the certain communication device in relation to (e.g., in contrastto) the signal characteristics of other communication devices.

For instance, the detector component 118 can receive informationrelating to the communication conditions (e.g., communication conditionparameters) of the communication devices (e.g., 104, 106, and/or 108)associated with the base station 112 from the communication devices,base station 112, RAN 110, or other network component of thecommunication network 102, such as described herein. The communicationcondition parameters associated with a communication device (e.g., 104,106, or 108) can comprise, for example, RSSI, RSRP, RSRQ, CQI, SINR,and/or TA associated with the communication device, and/or anotherdesired measurement or value relating to communication conditions, suchas described herein. The RSSI, RSRP, and RSRQ can indicate signalquality or signal power, which typically can have relatively lowvariance over time with regard to communication devices that do notchange position (e.g., location). The CQI can indicate the quality ofthe communication channel, wherein the CQI can have a range of valuesthat can range from a low number (e.g., 0), which can indicate a low,poor, or bad quality of the communication channel, to a high number(e.g., 30), which can indicate a high or good quality communicationchannel. The TA parameter can be calculated by the base station 112 todetermine the round-trip time delay of messages from the base station112 to a communication device (e.g., 104, 106, or 108) and back to thebase station 112. The TA parameter can have a relatively highcorrelation with the distance (e.g., radius) of the communication devicefrom the antenna of the base station 112.

There can be many communication devices (e.g., 104, 106, and/or 108)that can be stationary or fixed at a location, or at least can besubstantially stationary (e.g., not moved very often over a period oftime and/or only moved over a small distance, such as moved while insidea house, over the period of time). As a result, such communicationdevices often can have same or similar communication conditions (e.g.,same or similar RSSI, same or similar RSRP, same or similar RSRQ, sameor similar CQI, same or similar SINR, or same or similar TA) over aperiod of time. This can enable the detector component 118 to utilizethe respective measurement values of the respective communicationconditions of respective communication devices (e.g., 104, 106, and/or108) to identify the respective communication devices. Even in instanceswhere a communication device is moving, the detector component 118(e.g., employing the aggressive device detector component 204) often candetermine, predict, or infer measurement values (e.g., changes inmeasurement values) of communication conditions of the communicationdevice as the device is moving based at least in part on the speed ofmovement of the communication device, the location of the communicationdevice relative to the base station 112, the direction of movement ofthe communication device relative to the base station 112, and/or otherdesired factors. For example, if a communication device is traveling ina car down a highway at a certain speed, the detector component 118 canor may be able to determine, predict, or infer measurement values (e.g.,changes in measurement values) of communication conditions of thecommunication device as the device is moving down the highway based atleast in part on the speed, the location, and/or the direction ofmovement of the communication device relative to the base station 112,and/or other desired factors.

The aggressive device detector component 204 can analyze the informationrelating to the communication conditions of the communication devices(e.g., 104, 106, and/or 108). Based at least in part on the results ofanalyzing the information relating to the communication conditions, theaggressive device detector component 204 can determine or identifymeasurements of communication conditions (e.g., signal characteristics)that can identify (e.g., can be a communication signature of) acommunication device (e.g., 104, 106, or 108), wherein, for example,multiple same or similar measurements of communication conditions canindicate that such communication conditions can be associated with thesame communication device. For example, a first communication device(e.g., 104) can have a first TA value, and a second communication device(e.g., 106) can have a second TA value. The aggressive device detectorcomponent 204 can distinguish between and identify the firstcommunication device and the second communication device based at leastin part on the first TA value associated with the first communicationdevice and the second TA value associated with the second communicationdevice.

In some embodiments, the aggressive device detector component 204 candetermine (e.g., calculate) a calculated parameter value for acommunication device (e.g., 104, 106, or 108) based at least in part on(e.g., as a function of or as a combination of) a group of communicationcondition parameters (e.g., RSSI, RSRP, RSRQ, CQI, SINR, TA, and/oranother desired communication condition parameter) associated with thecommunication device, wherein the calculated parameter value canrepresent, at least in part, the communication signature associated withthe communication device. For instance, the aggressive device detectorcomponent 204 can determine a first calculated parameter valueassociated with a first communication device (e.g., 104) based at leastin part on a first group of communication condition parametersassociated with the first communication device, and can determine asecond calculated parameter value associated with a second communicationdevice (e.g., 106) based at least in part on a second group ofcommunication condition parameters associated with the secondcommunication device. The aggressive device detector component 204 candistinguish between and identify the first communication device (e.g.,104) and the second communication device (e.g., 106) based at least inpart on the results of analyzing the first calculated parameter valueassociated with the first communication device and the second calculatedparameter value associated with the second communication device.

By identifying or determining the respective signal characteristics(e.g., respective communication signatures) of the respectivecommunication devices, the aggressive device detector component 204 cancorrelate signals or messages associated with different temporaryidentifiers and can attribute all of those signals or messages to asingle communication device (e.g., an aggressive or excessive signaling,and/or malicious acting, communication device), even though such signalsor messages are associated with different temporary identifiers. Forexample, the cell or associated base station 112 can receive a set ofsignals (e.g., control signals, other type of signals, or messages) withtemporal identifiers from communication devices (e.g., 104, 106, and/or108), wherein the set of signals can comprise a first signal associatedwith a first temporal identifier (e.g., 10), a second signal associatedwith a second temporal identifier (e.g., 20), a third signal associatedwith a third temporal identifier (e.g., 30), a fourth signal associatedwith a fourth temporal identifier (e.g., 50), a fifth signal associatedwith a fifth temporal identifier (e.g., 60), a sixth signal associatedwith a sixth temporal identifier (e.g., 90), a seventh signal associatedwith a seventh temporal identifier (e.g., 110), and an eighth signalassociated with an eighth temporal identifier (e.g., 160).

The aggressive device detector component 204 can analyze the respectivesignal characteristics (e.g., RSSI, RSRP, RSRQ, CQI, SINR, TA, and/orother type of signal characteristic (e.g., communication condition))associated with the respective signals of the respective signals of theset of signals. Based at least in part on the results of analyzing thesignal characteristics of the respective signals, the aggressive devicedetector component 204 can determine or identify that the respectivesignal characteristics of the second signal, fourth signal, fifthsignal, seventh signal, and eighth signal can be the same orsubstantially the same as each other, while the first signal, thirdsignal, and sixth signal can have relatively different signalcharacteristics than the second, fourth, fifth, seventh, and eighthsignals. As a further result of such analysis, the aggressive devicedetector component 204 can determine that a subset of the signals (e.g.,the second signal, fourth signal, fifth signal, seventh signal, andeighth signal) can be attributed to the same communication device (e.g.,104), based at least in part on the result of determining that therespective signal characteristics of the respective signals of thesubset of signals are the same or substantially the same as each other(e.g., same or similar RSSI values, same or similar RSRP values, same orsimilar RSRQ values, same or similar CQI values, same or similar SINRvalues, same or similar TA values, and/or same or similar othercommunication condition parameter values), even though the secondsignal, fourth signal, fifth signal, seventh signal, and eighth signalare associated with different temporal identifiers. The aggressivedevice detector component 204 also can determine that the other signals(e.g., the first signal, third signal, and sixth signal) can beattributed to one or more other communication devices (e.g., 106 and/or108) based at least in part on the analysis results indicating that thesignal characteristics of these other signals are significantlydifferent from the signal characteristics of the subset of signalsattributed to the other communication device (e.g., 104).

While in many (e.g., most) cases a combination of measurements ofcommunication conditions can provide a sufficient communicationsignature associated with a communication device, there stillpotentially can be cases where false positives can occur with regard tothe identification of a communication device or whether a communicationdevice is acting in a benign manner or is engaging in excessivesignaling (e.g., where a benign communication device has similarmeasurements of communication conditions as an excessive signalingcommunication device). In some embodiments, to improve (e.g., increase)accuracy in identifying communication devices, in addition to analyzingcommunication conditions associated with communication devices, theaggressive device detector component 204 can analyze respectiveconfiguration parameters and/or other information associated withrespective communication devices (e.g., 104, 106, and/or 108) tofacilitate identifying communication devices. As disclosed herein, theconfiguration parameters associated with a communication device cancomprise, for example, QCI, ARP, MME/AMF code, MME/AMF group identifier,band frequency, or other desired configuration parameter associated withthe communication device. Different communication devices can or mayhave a different configuration parameter or different groups ofconfiguration parameters, which the aggressive device detector component204 can utilize to facilitate distinguishing between and identifyingcommunication devices. The aggressive device detector component 204 cananalyze the configuration parameters, for example, to confirm anidentification of a communication device that was determined based onthe communication conditions associated with that communication device,improve (e.g., increase) or at least attempt to improve, a confidencelevel in the identification of the communication device, and/oreliminate false positives. In certain embodiments, the aggressive devicedetector component 204 can determine (e.g., calculate) a calculatedparameter value for a communication device (e.g., 104, 106, or 108)based at least in part on (e.g., as a function of) the group ofcommunication condition parameters and a group of configurationparameters (e.g., QCI, ARP, MME/AMF code, MME/AMF group identifier, bandfrequency, and/or another desired configuration parameter) associatedwith the communication device, wherein the calculated parameter valuecan represent, at least in part, the communication signature associatedwith the communication device.

The aggressive device detector component 204 can evaluate one or morecommunication devices (e.g., identified communication devices)associated with the base station 112, and, for each communication device(e.g., 104, 106, or 108), can determine whether to classify thecommunication device as an excessive signaling communication devicebased at least in part on whether the number of control signals receivedfrom the communication device by the base station 112 during the definedtime period satisfies a defined threshold number of control signals thatcan be indicative of excessive signaling by the communication device, inaccordance with the defined communication management criteria.

If the aggressive device detector component 204 determines that nocommunication device satisfies the defined threshold number of controlsignals, the aggressive device detector component 204 can determine thatno excessive signaling or malicious communication device has beendetected. The detector component 118 can continue to monitorcommunication devices associated with the RAN 110 to detect whether anyexcessive signaling or malicious communication devices are actingagainst the RAN 110. If, instead, the aggressive device detectorcomponent 204 determines that a communication device (e.g., 104, 106, or108) satisfies (e.g., breaches, or meets or exceeds) the definedthreshold number of control signals, the aggressive device detectorcomponent 204 can determine that the communication device is anexcessive signaling communication device.

Referring briefly to FIGS. 3 and 4 (along with FIGS. 1 and 2 ), FIGS. 3and 4 depict diagrams of example graphs 300 and 400, respectively, ofrespective attach activity for respective single cells over a one-minuteperiod, in accordance with various aspects and embodiments of thedisclosed subject matter. The cell activity levels are considered to berelatively moderate to higher than normal. The example graph 300presents time (e.g., the one-minute period) on the x-axis, andcalculated parameter value on the y-axis, wherein the detector component118 (e.g., employing the aggressive device detector component 204) candetermine (e.g., calculate) the calculated parameter values based atleast in part on (e.g., as a function of) the group of communicationcondition parameters and the group of configuration parameters of eachof the communication devices. The example graph 300 illustrates thatthere are 45 attach events (e.g., attach event 302, attach event 304,attach event 306, attach event 308, attach event 310) at the cell overthe one-minute period. Based at least in part on the results ofanalyzing the attach events, the aggressive device detector component204 can attribute 15 of the attach events to 11 communication devices(e.g., benign acting communication devices), and can attribute the other30 attach events to a single excessive signaling communication device,which can be identified by the aggressive device detector component 204based at least in part on the single excessive signaling communicationdevice having a substantially consistent communication signature, asindicated by calculated parameter values of the excessive signalingcommunication device being substantially consistent for the attachevents (e.g., attach event 302, attach event 304, attach event 306) overthe one-minute period, as illustrated at reference numeral 312.

The example graph 400 of FIG. 4 presents time (e.g., the one-minuteperiod) on the x-axis, and calculated parameter value on the y-axis,wherein the detector component 118 (e.g., employing the aggressivedevice detector component 204) can determine the calculated parametervalues based at least in part on the group of communication conditionparameters and the group of configuration parameters of each of thecommunication devices. The example graph 400 illustrates that there are107 attach events (e.g., attach event 402, attach event 404, attachevent 406, attach event 408, attach event 410) at this other cell over aone-minute period. Based at least in part on the results of analyzingthe attach events, the aggressive device detector component 204 canattribute 63 of those attach events to 36 communication devices (e.g.,benign acting communication devices), and can attribute the other 44attach events to a single excessive signaling communication device,which can be identified by the aggressive device detector component 204based at least in part on the single excessive signaling communicationdevice having a substantially consistent communication signature, asindicated by the calculated parameter values of the excessive signalingcommunication device being substantially consistent for the attachevents (e.g., event 402, attach event 404, attach event 406) over theone-minute period, as illustrated at reference numeral 412.

With further regard to FIGS. 1 and 2 , in response to determining that acommunication device(s) (e.g., 104, 106, or 108) is an excessivesignaling and/or malicious acting communication device, the detectorcomponent 118 (e.g., employing the aggressive device detector component204) can determine (e.g., calculate) and generate a set of statisticsrelating to the excessive signaling of the communication device(s), asindicated at reference numeral 208. In accordance with variousembodiments, the detector component 118 can determine and generate a setof statistics with regard to an individual excessive signalingcommunication device, or can determine and generate a set of statisticsfor a group of excessive signaling communication devices. The set ofstatistics can provide desired (e.g., relevant or suitable) informationregarding the excessive signaling to enable the SMC 116 or user to learnmore about the excessive signaling and/or to facilitate makingdeterminations regarding how to respond to the excessive signaling(e.g., taking mitigation action to mitigate the excessive signaling).The set of statistics can comprise a device identifier (e.g., UE_ID)that the detector component 118 can assign to an excessive signalingcommunication device to facilitate identifying the communication device(e.g., since the IMEI and IMSI are not available to the detectorcomponent 118).

The set of statistics also can comprise an exception level, which canindicate the how exceptional or concerning the excessive signaling ofthe excessive signaling communication device is. The detector component118 can determine the exception level based at least in part on one ormore defined threshold exception levels and the results of analyzinginformation relating to the excessive signaling of a communicationdevice. The exception levels can relate to respective responsecategories, such as, for example, alert (e.g., alert the SMC 116,communication network 102, or user about the detected excessivesignaling), log and learn (e.g., track and log more informationregarding the excessive signaling to learn more about the excessivesignaling and/or excessive signaling device(s)), throttle (e.g.,recommend, suggest, or indicate that the excessive signaling isparticularly problematic or harmful, or potentially harmful, to the RAN110, base station 112, or communication network 102, and throttling(e.g., partially blocking) of the excessive signaling device(s) to blockat least a portion of the attempts by the device to attach to, connectto, or communicate with the base station 112 (or other base stations)may be warranted), block (e.g., recommend, suggest, or indicate that theexcessive signaling is particularly problematic or harmful, orpotentially harmful, to the RAN 110, base station 112, or communicationnetwork 102, and blocking of the excessive signaling device(s) may bewarranted), or another desired response category. If the detectorcomponent 118 determines that a lower defined threshold exception levelhas been satisfied with regard to an excessive signaling communicationdevice, the detector component 118 can assign a relatively lowerexception level (e.g., alert exception level, or log and learn exceptionlevel) to the excessive signaling communication device. If the detectorcomponent 118 determines that a higher (e.g., highest) defined thresholdexception level has been satisfied with regard to an excessive signalingcommunication device, the detector component 118 can assign a higherexception level (e.g., block exception level) to the excessive signalingcommunication device.

The set of statistics also can comprise an exception trend. Based atleast in part on the results of analyzing information relating to theexcessive signaling of a communication device, the detector component118 can determine an exception trend of the signaling by thecommunication device. For instance, if the detector component 118determines that the signaling by the excessive signaling communicationdevice has been increasing over time, the detector component 118 candetermine that the excessive signaling is trending upward and canindicate that the exception trend is upward. If, instead, the detectorcomponent 118 determines that the signaling by the excessive signalingcommunication device has been decreasing over time, the detectorcomponent 118 can determine that the excessive signaling is trendingdownward and can indicate that the exception trend is downward. If,instead, the detector component 118 determines that the signaling by theexcessive signaling communication device has been relatively stable overtime, the detector component 118 can determine that the excessivesignaling is relatively stable and can indicate that the exception trendis stable. If, instead, the detector component 118 is unable todetermine the trend of the signaling by the excessive signalingcommunication device, the detector component 118 can indicate that theexception trend is unknown.

In some embodiments, the set of statistics can comprise calculatedperiodic communication values. For example, the detector component 118can determine an average number of control signals (e.g., attachsignals, update signals, or other type of control signal) associatedwith an excessive signaling communication device over each time periodof a set of time periods. The average number can be or represent a trueaverage, a median, a mean, a mode, or other mid-point value that canrepresent or indicate a level or frequency of control signaling over aparticular time period. As another example, the detector component 118can determine a variance value relating to the communication of controlsignals by an excessive signaling communication device. The variancevalue can indicate whether there is one or more spikes (e.g., peaks) incontrol signaling by the excessive signaling communication device (e.g.,one or more time periods where the excessive signaling spikes higherrelative to one or more other time periods where the signaling isrelatively lower). The detector component 118 can determine theexception trend based at least in part on the periodic communicationvalues.

The set of statistics also can include time information, such as a starttime(s) and end time(s), associated with the various other statistics ofthe set of statistics. For instance, a start and stop time can be over aone-minute period, a one-hour period, a one-day period, a one-weekperiod, a one-month period, a one-year period, or other desired periodof time.

The set of statistics further can comprise a confidence level(s) thatcan indicate the level of confidence in the identification of acommunication device, the level of confidence in a determination that acommunication device is an excessive signaling and/or maliciously actingcommunication device, and/or an overall confidence level relating to theidentification of the device and determination that it is an excessivesignaling device. The detector component 118 can determine (e.g.,calculate) a confidence level(s) based at least in part on the resultsof analyzing the group of communication condition parameters, the groupof configuration parameters, calculated parameter values, and/or otherdesired (e.g., relevant or suitable) information. For instance, if agroup of calculated parameter values are relatively consistent (e.g.,same or substantially the same) over a period of time, the detectorcomponent 118 can determine that there is a relatively high confidencelevel that the calculated parameter values of the group of calculatedparameter values are associated with a same communication device and thegroup of calculated parameter values can represent a communicationsignature of the communication device. If, instead, a group ofcalculated parameter values not very consistent (e.g., vary somewhatrelative to each other) over a period of time, the detector component118 can determine that there is a relatively lower confidence level thatthe calculated parameter values of the group of calculated parametervalues are associated with a same communication device.

As another example, if the detector component 118 determines that anidentified communication device has been excessively signaling on arelatively consistent basis over a number of periods of time, thedetector component 118 can determine that there is a relatively highconfidence level that the communication device is an excessive signalingcommunication device. If, instead, the detector component 118 determinesthat an identified communication device was excessively signaling on arelatively inconsistent basis over a number of periods of time (e.g.,where the device was determined to be excessively signaling over one ora small number of periods of time, but not excessive signaling over mostof the periods of time under consideration), the detector component 118can determine that there is a relatively lower confidence level that thecommunication device is an excessive signaling communication device.

In certain embodiments, to facilitate determining whether acommunication device is an aggressive (e.g., excessive signaling and/ormalicious acting) communication device, determining a level ofaggressiveness (e.g., excessive signaling) of an excessive signalingcommunication device, and/or determining a type of communication devicethat is engaging in aggressive behavior against the RAN 110, thedetector component 118 can comprise a device type reputation component210 that can receive information relating to device type reputations ofcommunication devices via a desired interface, such as A1 interface 212,from the core network of the communication network 102. Whileinformation relating to device type reputations of communication devicesmay not always be available to the detector component 118, in someinstance, the detector component 118 (e.g., employing the device typereputation component 210) can obtain such information from the corenetwork.

For example, if a communication device (e.g., 104) is an aggressivecommunication device that was not yet identified as aggressive (e.g.,excessive signaling) by the detector component 118 or was not blocked bythe SMC 116, the communication can be allowed to continue itsregistration attempt all the way to the core network (e.g., usingnon-access stratum (NAS) messages). In such instances, the deviceidentifiers (e.g., IMEI, IMSI) can be revealed to the core network andinformation relating to the device identifiers (but not the deviceidentifiers themselves) can be received by the device type reputationcomponent 210 via the A1 interface 212.

Such information can comprise the device vendor and model of acommunication device, which can be represented in the type allocationcode (TAC) associated with the communication device (e.g., 104). The TACof a communication device can be mapped to the C-RNTI and/or TMSI,wherein such mapping can be part of the information relating to thedevice type reputation device that can be received by the device typereputation component 210. The device type reputation information can beuseful to facilitate detecting aggressive communication devices of acertain type (e.g., device vendor and/or device model) that can orpotentially can engage in common aggressive behavior (e.g., due to avulnerability in the type of communication device that renders itsusceptible to being infected with malware).

The device type reputation component 210 can maintain informationrelating to the device type reputations of devices, includinginformation regarding common aggressive behavior of certain types (e.g.,certain device vendor(s) and/or device model(s)) of communicationdevices. The device type reputation component 210 also can maintaininformation regarding signaling patterns of certain types ofcommunication devices. The device type reputation component 210 canprovide such information relating to the device type reputations ofdevices to the aggressive device detector component 204 for use by theaggressive device detector component 204 to facilitate detectingaggressive communication devices and/or determining when certain typesof communication devices, while engaging in relatively higher levels ofcommunicating control signaling than other communication devices, arenot aggressive signaling devices, but rather are devices that merelyengage in more signaling than other types of communication devices.Information relating to the device type reputations of devices, such as,for example, certain information relating to certain types (e.g.,certain device vendor(s) and/or device model(s)) of communicationdevices, can be attributed to all future attempts (e.g., attach attemptsor other control signaling) to signal the core network by communicationdevices of that certain type, as the temporary identifiers of thecertain types of communication devices can be mapped to the TAC.

Information relating to common aggressive behavior of certain types ofcommunication devices can be useful (e.g., helpful) in cases, forexample, where the detector component 118 can know a-priory that acertain device model has a vulnerability that can cause the certaindevice model of communication device to undesirably (e.g., excessively)attempt to attach to the core network once every two seconds, or anotherparticular device model has a vulnerability that can cause theparticular device model of communication device to undesirably (e.g.,excessively) attempt to attach to the core network every time theparticular device model of communication device is moved. As part of itsanalysis to determine whether a communication device(s) is an aggressive(e.g., excessive signaling) communication device, the aggressive devicedetector component 204 can analyze the information relating to devicetype information, the information relating to cell classification, andother received information (e.g., information relating to communicationconditions, and/or information relating to configuration parameters),and based at least in part on the analysis results, can determinewhether a communication device(s) is an aggressive communicationdevices(s), in accordance with the defined communication managementcriteria. This can enable the aggressive device detector component 204to more accurately determine whether a communication device is anaggressive communication device or not (e.g., can reduce false positivedeterminations of aggressive signaling by devices, and/or can reducefalse positive determinations of benign actions by communication devicesthat actually are aggressive communication devices).

As another example, a particular type of communication device (e.g.,particular device vendor(s) and/or device model(s)) can, as part ofnormal operation, communicate a relatively higher number of controlsignals to the base station 112 than other types of communicationdevices. The aggressive device detector component 204 can receiveinformation relating to the device type information of such particulartype of communication device from the device type reputation component210, and can take into account (e.g., incorporate into its analysis)that this particular type of communication device, as part of its normaloperation, communicates a relatively higher number of control signals tothe base stations. This can enable the aggressive device detectorcomponent 204 to be more accurate in determining whether a communicationdevice (e.g., the particular type of communication device) is anaggressive communication device or not, as this can reduce falsepositive determinations that this particular type of communicationdevice is an aggressive communication device in instances where suchcommunication device is merely engaging in normal (albeit a relativelyhigher level of) communication of control signaling to a base station.

In some embodiments, the SMC 116 can comprise a connection managercomponent 120 that can determine whether to perform a mitigation actionor other action (e.g., logging and learning action, alert action) withregard to an aggressive (e.g., excessive signaling) communication device(e.g., 104) based at least in part on the information, including the setof statistics, received from the detector component 118, in accordancewith the defined communication management criteria. For example, if,based at least in part on the results of the analysis of the set ofstatistics and/or other information relating to a communication device(e.g., 104), the connection manager component 120 determines that theexception level is not too high (e.g., level of excessive signaling isnot too high) and/or the exception trend is not indicating that theexcessive signaling is trending upward, the connection manager component120 can or may determine that an action(s), such as an alert action or alogging and learning action, other than blocking or throttling of thecommunication device (e.g., 104) can be the action(s) to be performed(e.g., by the SMC 116), when doing so is in accordance with the definedcommunication management criteria. In response to determining that analert action or a logging and learning action is to be performed withregard to the communication device (e.g., 104), the connection managercomponent 120 can generate alert instructions or logging and learninginstructions and can communicate the alert instructions or logging andlearning instructions to the RAN 110, base station 112, the detectorcomponent 118, another component of the SMC 116, or another component ofthe communication network 102. In response to such instructions, the RAN110, base station 112, the detector component 118, another component ofthe SMC 116, or another component of the communication network 102 cangenerate an alert regarding the excessive signaling communication device(e.g., to alert a user or a component of or associated with the corenetwork regarding the excessive signaling communication device), or canlog information regarding the excessive signaling communication deviceto facilitate learning more about the excessive signaling communicationdevice, other similar excessive signaling communication devices, and/orvulnerabilities or malware associated with the excessive signalingcommunication device.

As another example, if, based at least in part on the results of theanalysis of the set of statistics and/or other information relating to acommunication device (e.g., 104), the connection manager component 120determines that the exception level is relatively high (e.g., level ofexcessive signaling is relatively high) and/or the exception trend isindicating that the excessive signaling is trending upward (e.g., and isat or is heading towards a relatively high level), the connectionmanager component 120 can or may determine that a mitigation action toblock or throttle the communication device (e.g., 104) can be theaction(s) to be performed (e.g., by the SMC 116), when doing so is inaccordance with the defined communication management criteria. Inresponse to determining that the mitigation action to block thecommunication device (e.g., 104) is to be performed, the connectionmanager component 120 can generate blocking instructions and cancommunicate the blocking instructions to the base station 112. Inresponse to the blocking instructions, the base station 112 can block ordisconnect the excessive signaling communication device (e.g., 104) todisconnect the communication from the base station 112 or prevent thecommunication device from the connecting to the base station 112. Inresponse to determining that the mitigation action to throttle (e.g.,partially block) the communication device (e.g., 104) is to beperformed, the connection manager component 120 can generate throttlinginstructions and can communicate the throttling instructions to the basestation 112. In response to the throttling instructions, the basestation 112 can throttle the communication device block at least adesired portion (e.g., 50%, 60%, 70%, 80%, or other desired portiongreater or less than 80%) of the attempts of the excessive signalingcommunication device (e.g., 104) to attach to, connect to, orcommunicate with the base station 112 (or other base stations or cells,such as other base stations or cells associated with the RAN 110).

For instance, with regard to blocking or disconnecting of an excessivesignaling communication device (e.g., 104) by or from the base station112, even though the SMC 116 does not know the permanent device orsubscriber identifiers (e.g., IMEI, IMSI) associated with the excessivesignaling communication device, the detector component 118 hasidentified the communication signature of the excessive signalingcommunication device. To facilitate blocking or disconnecting theexcessive signaling communication device (e.g., 104), the connectionmanager component 120 can instruct the RAN 110 or base station 112 toblock or disconnect all or some (e.g., a desired portion or percentageof) communication devices that have a communication signature that issame as or substantially similar to the communication signatureidentified for the excessive signaling communication device (e.g., 104),which will, or at least very likely will, result in the blocking ordisconnecting of the excessive signaling communication device (e.g.,104) by or from the base station 112. For example, if the excessivesignaling communication device (e.g., 104) has a particular calculatedparameter value, a particular communication condition value, or aparticular set of communication condition values, the connection managercomponent 120 can instruct the RAN 110 or base station 112 to block ordisconnect all or some communication devices that have a calculatedparameter value that falls in a range of calculated parameter valuesthat can be determined based at least in part on, and can comprise, theparticular calculated parameter value; block or disconnect all or somecommunication devices that have a communication condition value thatfalls in a range of communication condition values that can bedetermined based at least in part on, and can comprise, the particularcommunication condition value; or block or disconnect all or somecommunication devices that have a particular set of communicationcondition values where the respective communication condition values inthe set fall in respective ranges of communication condition values thatcan be determined based at least in part on, and can comprise, theparticular set of communication condition values. The connection managercomponent 120 can thereby effectively block the excessive signalingcommunication device (e.g., 104) without having to block benign acting(e.g., non-aggressive or non-malicious) communication devices (e.g., 106or 108), which can have communication signatures that can be differentfrom the communication signature of the excessive signalingcommunication device (e.g., 104).

Other aspects and embodiments of the disclosed subject matter will bedescribed with regard to the other figures (and/or FIG. 1 ).

Referring to FIG. 5 , FIG. 5 depicts a diagram of an example system 500comprising a RAN to which communication devices, including IoT devices,are attempting to connect or are already connected, wherein the RANcomprises an SMC that can detect and mitigate aggressive signalingand/or malicious events against the RAN and can manage connection ofcommunication devices to the RAN, in accordance with various aspects andembodiments of the disclosed subject matter. The system 500 can comprisea RAN 500 that can be part of a communication network (e.g., a mobilitycore network of a communication network). The RAN 502 can be the sameas, or can comprise the same or similar functionality as, RANs, such asmore fully described herein.

In an example instance, a plurality of communication devices 504,including IoT devices, can be attempting to connect (e.g., wirelesslyconnect) to the RAN 502 (or some of those devices may already beconnected to the RAN 502) as part of aggressive signaling and/or amalicious event (e.g., malicious attack or signaling storm) by thosecommunication devices 504 against the RAN 502. For instance, theplurality of communication devices 504 can be compromised communicationdevices (e.g., compromised massive IoT) that can be infected withmalware. In some embodiments, each of the plurality of communicationdevices 504 can communicate respective attach requests or othercommunications to the RAN 502 via an air interface (depicted atreference numeral 506) associated with the RAN 502 to an antennacomponent 508 of the RAN 502. In some embodiments, the antenna component508 can comprise a MIMO antenna array and radio unit to facilitatereceiving of information by the RAN 502 and transmitting of informationfrom the RAN 502.

The RAN 502 also can include a distributed unit (DU) component 510 thatcan comprise a DU function that can be associated with the radio unitand associated antenna component 508. The DU function in the 5GgNodeB/NR framework can comprise some of the functions that the baseband unit (BBU) of 4G/LTE has.

The RAN 502 also can comprise a CU-CP component 512 that can employ aCU-CP function in the 5G gNodeB/NR framework. The CU-CP function cancomprise certain functions (e.g., functions different from the DUfunction) that the BBU of 4g/LTE has. The DU component 510 can beassociated with (e.g., communicatively connected to) the CU-CP component512 via an F1-C interface 514 to facilitate data flows between the DUcomponent 510 and the CU-CP component 512.

The RAN 502 further can comprise a RAN intelligent controller (RIC) 516that can be associated with (e.g., communicatively connected to) theCU-CP component 512 via an E2 interface 518, wherein the E2 interfacecan facilitate data flows between the CU-CP component 512 and the RIC516. The RIC 516 can manage various functions and resources of the RAN502 in real time or substantially close (e.g., near) to real time.

The RAN 502 can comprise an SMC 520 that can detect and mitigateaggressive (e.g., excessive) signaling and/or malicious events bycertain communication devices (e.g., plurality of communication devices504) against the RAN 502, and desirably managing connections ofcommunication devices to the RAN 502 during an aggressive signalingand/or malicious event to allow communication devices (e.g.,communication device 522) that are not determined to be aggressive ormalicious, and/or are associated with a higher priority, to connect tothe RAN 502 and block (e.g., prevent or discontinue connections of)other communication devices (including the plurality of communicationdevices 504) determined to be acting in an aggressive (e.g., excessivesignaling) and/or malicious manner from connecting to the RAN 502, inaccordance with the defined network security criteria. In someembodiments, the SMC 520 can comprise and employ a security application(e.g., aggressive signaling, malicious event, and/or DDoS application)to facilitate detecting and mitigating aggressive signaling and/ormalicious events against the RAN 502, and managing connections ofcommunication devices to the RAN 502. The security application can be amicro services application (e.g., xApp), for example. The SMC 520 canprovide an intelligent security capability using machine learning toenhance the detection and mitigation of aggressive signaling and/ormalicious threats or events against the RAN 502 caused by certaincommunication devices (e.g., caused by signaling storms by means ofmassive IoT through the plurality of communication devices 504). The SMC520 can be the same as, or can comprise the same or similarfunctionality as, the SMCs, as more fully described herein.

Referring to FIGS. 6 and 7 (along with FIG. 5 ), FIG. 6 depicts a blockdiagram of an example network security flow 600 relating to variousfunctions that can be performed by the SMC 520, and FIG. 7 illustrates ablock diagram of the example SMC 520, including various components ofthe SMC 520, in accordance with various aspects and embodiments of thedisclosed subject matter. As part of the example network security flow600, information relating to communication devices attempting to connectto, or already connected to, the RAN 502 (e.g., communication devicessubmitting attach requests or other communications to the RAN 502) canbe received by the RIC 516, and associated SMC 520, from the CU-CPcomponent 512 via the E2 interface 518 (as depicted at reference numeral602 of FIG. 6 ). The information, which can comprise real-timeRAN-related data (e.g., 5G RAN data), can include, for example, attachrequest information relating to attach requests, other types of controlsignals, metadata, and/or other types of information relating tocommunication devices or associated messages, communicated to the RAN502 by communication devices via the air interface 506 and antennacomponent 508. The communication devices can include, for example,communication device 522 and the plurality of communication devices 504.

The SMC 520 can comprise a parser component 702 that can collect andparse the information, including the information relating tocommunication devices (e.g., communication device 522 and plurality ofcommunication devices 504) and/or associated messages, in real time orat least substantially real time (as depicted at reference numeral 604of FIG. 6 ). The parser component 702 can analyze the information (e.g.,attach request information, other types of control signals, metadata, orother types of information) relating to the communication devices and/orassociated messages, and based at least in part on the results of suchparsing analysis, the parser component 702 can determine or identifyrespective items of information in the information relating to thecommunication devices and/or associated messages. The parser component702 can parse such information to facilitate determining relevantinformation from the information relating to the communication devicesand/or associated messages.

In some embodiments, the SMC 520 also can include a filter component 704that can be associated with (e.g., communicatively connected to) theparser component 702. The filter component 704 can filter (e.g.,intelligently filter) the parsed information, can determine (e.g.,intelligently determine) relevant information from the parsedinformation, filter the parsed information to generate filteredinformation comprising the relevant information, and purge otherinformation of the parsed information that is determined to not besufficiently relevant (as shown at reference numeral 606 of FIG. 6 ).The relevant information can comprise information determined to berelevant for use in determining whether an aggressive and/or maliciousevent against the RAN 502 by certain communication devices (e.g.,plurality of communication devices 504) is occurring, in accordance withthe defined network security criteria (e.g., network security criteriathat can indicate what types of information can be relevant todetermining aggressive and/or malicious events against the RAN 502). Insome embodiments, the filter component 704 can filter the parsedinformation to generate the filtered information in real time or atleast substantially in real time.

In certain embodiments, the filter component 704 can communicate theparsed information and/or other parsing and/or filtering-relatedinformation to a machine learning component 706 of the SMC 520 foranalysis (e.g., machine learning analysis) (as indicated at referencenumeral 608 of FIG. 6 ). The machine learning component 706 can employmachine learning techniques and algorithms to perform analysis on theparsed information and/or other parsing and/or filtering-relatedinformation to learn (e.g., continuously learn) how to improve theparsing and/or filtering (e.g., intelligent filtering) of informationrelating to communication devices and/or other RAN-related data todetermine relevant information and facilitate detection of aggressiveand/or malicious events against the RAN 502 (as indicated at referencenumeral 610). For instance, based at least in part on the results of theanalysis (e.g., machine learning analysis) of the parsed information,the other parsing and/or filtering-related information, and/orhistorical (e.g., previous) parsed information and/or other historicalparsing and/or filtering-related information, the machine learningcomponent 706 can learn (e.g., learn in real time, and/or learn overtime) what types of information can be more relevant, and what othertypes of information can be relatively less relevant or irrelevant, todeterminations regarding whether an aggressive and/or malicious event bycommunication devices (e.g., plurality of communication devices 504) isoccurring.

For instance, the machine learning component 706 can employ the machinelearning techniques and algorithms to learn how to enhance parsing andfiltering of information relating communication devices to facilitatedetermining relevant information from the information relatingcommunication devices and/or associated messages, filtering theinformation to generate the filtered information, comprising therelevant information, and purging undesired information (e.g.,information determined to not be sufficiently relevant), in accordancewith the defined network security criteria. Based at least in part onthe results of such analysis and learning by the machine learningcomponent 706, the machine learning component 706 can determine parsingand/or filtering update information (e.g., feedback information)relating to such enhancement of the parsing and filtering of theinformation relating communication devices and/or associated messages.

The machine learning component 706 can communicate the parsing and/orfiltering update information to the parser component 702 and/or filtercomponent 704 (as shown at reference numeral 612 of FIG. 6 ). The parsercomponent 702 can utilize the parsing update information to update andenhance the parsing functions of the parser component 702. The filtercomponent 704 can utilize the filtering update information to update andenhance the filtering functions of the filter component 704.

For instance, an update of the filtering functions of the filtercomponent 704 can enhance determinations regarding which types ofinformation associated with communication devices are relevant, or morerelevant (e.g., more relevant than other types of information), whendetermining whether an aggressive and/or malicious event against the RAN502 is occurring. For example, at a first time, it can be determinedthat a particular type of information is not particularly relevant todetermining whether a malicious event against the RAN 502 is occurring,and therefore, the filtering criteria utilized by the filter component704 can result in that particular type of information not being includedin the filtered or relevant information. Based at least in part onanalysis results of analyzing information relating to communicationdevices, the parsed information, and/or other desired information, themachine learning component 706 can learn that the particular type ofinformation actually does have sufficient relevance to determiningwhether an aggressive and/or malicious event against the RAN 502 isoccurring. Accordingly, the machine learning component 706 can generatefiltering update information that can indicate that the particular typeof information is relevant to determining whether an aggressive and/ormalicious event against the RAN 502 is occurring, and the filteringfunctions of the filter component 704 can be updated, based at least inpart on such filtering update information, such that the filtercomponent 704, when subsequently analyzing and filtering parsedinformation, can determine that the particular type of information (ifin the parsed information) can be relevant and can include it in thefiltered (e.g., relevant) information generated by the filter component704 and sent to the detector component 708 of the SMC 520.

In some embodiments, the machine learning component 706 also candetermine an initial or continuous (e.g., adapted) baseline (e.g., adefined baseline), based at least in part on the results of the analysisof the parsed information and/or other parsing and/or filtering-relatedinformation, previous analysis of historical (e.g., previous) parsedinformation and/or other parsing and/or filtering-related information,and/or other desired information (as indicated at reference numeral 610of FIG. 6 ). The other desired information can comprise, for example,information relating to aggressive and/or malicious event determinationsmade by and received from the detector component 708. The definedbaseline (e.g., initial or continuous baseline) can be utilized by thedetector component 708 to facilitate detecting or determining whether anaggressive and/or malicious event (e.g., excessive or aggressivesignaling) against the RAN 502 by certain communication devices (e.g.,plurality of communication devices 504) is occurring or at leastpotentially is occurring, as more fully described herein. The definedbaseline can specify respective baseline parameters (e.g., respectivethreshold parameter values) regarding respective characteristicsassociated with the communication devices. If all or a sufficient numberof the respective baseline parameters are determined to be satisfied(e.g., met or exceeded, or breached), for example, by the detectorcomponent 708, a determination can be made that an aggressive and/ormalicious event against the RAN 502 by certain communication devices(e.g., plurality of communication devices 504) is occurring or at leastpotentially is occurring, in accordance with the defined networksecurity criteria.

In certain embodiments, the machine learning component 706 can applyrespective weights to the respective baseline parameters of the definedbaseline, based at least in part the determined respective significanceof the respective baseline parameters, in accordance with the definednetwork security criteria. For example, the machine learning component706 can determine that a first baseline parameter can be more relevantor significant in determining whether a malicious event against the RAN502 is occurring than a second baseline parameter, and accordingly, themachine learning component 706 can apply a first weight (e.g., a higherweight) to the first baseline parameter and a second weight (e.g., arelatively lower weight) to the second baseline parameter. The baselineparameters of the defined baseline can comprise various types ofparameters (e.g., communication condition parameters associated withcommunication devices, configuration parameters associated withcommunication devices, location of cell or base station, terrain orgeography associated with a cell or base station, locations ofcommunication devices, type of attach request or other communication,time of attach request or other communication, number of communicationdevices in a given area, type of communication device, vendor or modelof communication device, and/or another desired parameter or factor),such as those parameters described herein or any other desired type ofparameter.

The machine learning component 706 can learn, based at least in part oncontinued analysis of parsed information, other parsing and/orfiltering-related information, aggressive and/or malicious eventdetermination-related information, external information relating toaggressive and/or malicious event determinations, and/or other desiredinformation, enhancements that can be made to the defined baseline,including respective baseline parameters, to enhance the detection ofaggressive and/or malicious events against the RAN 502. Based at leastin part on such learning and enhancements, the machine learningcomponent 706 can modify (e.g., adapt, adjust, change, or update) thedefined baseline to generate an updated defined baseline (or updateinformation that can be used to update the defined baseline), inaccordance with the defined network security criteria.

Referring again to the filter component 704, the filter component 704can communicate the filtered information, comprising the relevantinformation, associated with the communication devices (e.g.,communication device 522, plurality of communication devices 504, orother communication devices) to the detector component 708 for analysisby the detector component 708 (as depicted at reference numeral 614 ofFIG. 6 ). The detector component 708 can detect or determine aggressiveand/or malicious events (e.g., excessive signaling and/or otheraggressive or malicious attacks) by certain communication devices (e.g.,plurality of communication devices 504) against the RAN 502 (e.g.,during a DDoS attack by massive IoT against the RAN 502), based at leastin part on the defined baseline (e.g., initial baseline or updateddefined baseline, as applicable) and detection algorithms (as indicatedat reference numeral 616 of FIG. 6 ).

The detector component 708 can comprise a cell classifier component 710that can classify cells or associated base stations based at least inpart on a set of factors, such as, for example, the activity levelassociated with a cell, location of the cell, terrain and/or geographyof the cell site of the cell, and/or other desired factors. In someembodiments, the machine learning component 706 can be employed andtrained, using machine learning techniques and algorithms, to classifyor facilitate classifying cells and associated base stations, and canprovide update information to the cell classifier component 710 toupdate and refine the ability of the cell classifier component 710 tomore desirably (e.g., accurately, suitably, and/or efficiently) classifycells and/or associated base stations. For instance, the cell classifiercomponent 710 and/or machine learning component 706, using the machinelearning techniques and algorithms, can determine and build a profilefor each cell (and/or associated base station) of the core network,wherein the profile can comprise information relating to variousparameters, such as, for example, volume of connectivity and mobilityevents, signal power, signal quality, and behavior associated with thecell during various different times of the day, the week, the month, theyear, and/or with regard to special events (e.g., holidays, sportingevents, entertainment events, or other special events). These parameterscan vary for different cells, for example, based at least in part onwhether a cell site of a cell is located in a metropolitan area or arural area, the terrain and/or geography of the cell site of the cell,and/or other factors.

The detector component 708 also can comprise an aggressive devicedetector component 712 that can detect aggressive and/or maliciouscommunication devices (e.g., excessive signaling communication devices)acting against the RAN 502 (e.g., a cell or base station of the RAN502), based at least in part on the result of analyzing the filteredinformation, applicable defined threshold values relating to controlsignals, and/or other desired information, wherein the applicabledefined threshold values relating to control signals can be determinedbased at least in part on the defined baseline (initial or updatedbaseline), in accordance with the defined communication managementcriteria, which can comprise the defined network security criteria. Theaggressive device detector component 712 can receive input information(e.g., filtered input information) from the cell classifier component710 and, when available, from the device type reputation component 714,such as more fully described herein.

The applicable defined threshold values relating to control signals cancomprise, for example, an applicable defined threshold total number ofcontrol signals that can be associated with a cell or associated basestation, and can indicate whether there is unusual and/or potentiallyaggressive activity by communication devices associated with the cell orbase station, such as more fully described herein. The defined thresholdtotal number of control signals that can be applicable at the time ofsuch analysis can be based at least in part on a number of factors,which can include the classification of the cell or associated basestation, the type of control signal, whether one type or more than onetype of control signal is being considered, the length of the definedtime period, the time of day, time of week, time or month, or time ofyear when such analysis is being performed, and/or other desiredfactors. The applicable defined threshold values relating to controlsignals also can comprise, for example, an applicable defined thresholdnumber of control signals that can be applied with regard to acommunication device (e.g., identified communication device) associatedwith the cell or base station, and can indicate whether there is unusualand/or potentially aggressive activity (e.g., excessive signaling) bythat communication device, such as more fully described herein.

Employing the detection techniques and algorithms, the detectorcomponent 708 (e.g., employing the aggressive device detector component712) can analyze the filtered information, comprising the relevantinformation, relating to the communication devices and/or associatedmessages (e.g., control signals), in relation to the defined baseline(e.g., and associated defined threshold values relating to controlsignals), to facilitate determining whether an aggressive and/ormalicious event (e.g., aggressive and/or malicious attack) against theRAN 502 by at least some of the communication devices (e.g., pluralityof communication devices 504) is occurring. For instance, the detectorcomponent 708 can analyze the filtered information to determinerespective characteristics (e.g., communication of control signals,communication conditions, configuration parameters, and/or devicereputation characteristics) associated with the respective communicationdevices (e.g., communication device 522 and plurality of communicationdevices 504), wherein the respective characteristics associated with therespective communication devices can be utilized to facilitatedetermining whether there is an aggressive and/or malicious eventagainst the RAN 502 occurring. As part of the analysis, the detectorcomponent 708 can compare respective parameters (e.g., parameter values)of the respective characteristics against corresponding baselineparameters of the defined baseline to determine whether the definedbaseline has been satisfied (e.g., met or exceeded, or breached), which,if satisfied, can indicate that an aggressive and/or malicious eventagainst the RAN 502 is occurring.

In certain embodiments, the defined baseline can comprise one or morethreshold parameter values associated with one or more baselineparameters of one or more characteristics associated with communicationdevices. If a parameter value of a characteristic of the respectivecharacteristics associated with the communication devices satisfies(e.g., meets or exceeds (or is lower than, as applicable), or breaches)the applicable threshold parameter value, the detector component 708 candetermine that such satisfaction of the applicable threshold parametervalue can be indicative of an aggressive and/or malicious event againstthe RAN 502 occurring.

Based at least in part on the results of such analysis, including theresults of such comparison of respective parameters of the respectivecharacteristics to corresponding baseline parameters of the definedbaseline, the detector component 708 can determine whether the definedbaseline has been satisfied (e.g., met or exceeded, or breached), andaccordingly, can determine (e.g., can make at least a preliminary orinitial determination) whether an aggressive and/or malicious eventagainst the RAN 502 by at least some of the communication devices (e.g.,all or some of the plurality of communication devices 504) is occurring.

For instance, if, based at least in part on the comparison results fromthe comparison of respective parameters of the respectivecharacteristics to the defined baseline, the detector component 708determines that the defined baseline is satisfied and there issufficient evidence of an aggressive and/or malicious event against theRAN 502 occurring (e.g., due to certain parameter values of certainparameters associated with certain characteristics satisfying theirrespective defined threshold parameter values), the detector component708 can determine (e.g., can make a preliminary or initialdetermination) that an aggressive and/or malicious event against the RAN502 by at least some of the communication devices (e.g., some or all ofthe plurality of communication devices 504) is occurring, in accordancewith the defined network security criteria. Alternatively, if, based atleast in part on the comparison results from the comparison to thedefined baseline, the detector component 708 determines that the definedbaseline is not satisfied and there is not sufficient evidence of anaggressive and/or malicious event against the RAN 502 occurring (e.g.,due to a lack of certain parameter values of certain parametersassociated with certain characteristics satisfying their respectivedefined threshold parameter values), the detector component 708 candetermine (e.g., can make a preliminary or initial determination) thatthere is no aggressive or malicious event against the RAN 502 occurring,in accordance with the defined network security criteria.

If the detector component 708 determines that no aggressive or maliciousevent against the RAN 502 occurring, the detector component 708 cancommunicate information indicating no aggressive or malicious event isoccurring to a connection manager component 716 of the SMC 520.Accordingly, in response to receiving the information indicating that nomalicious event is occurring, the connection manager component 716 canallow the communication devices to connect to or remain connected to theRAN 502. The SMC 520 can continue to monitor the communication network,including the RAN 502 and communication devices attempting to connectto, or already connected to, the RAN 502.

If, instead, the detector component 708 determines (e.g., makes apreliminary or initial determination) that an aggressive and/ormalicious event against the RAN 502 by at least some of thecommunication devices (e.g., some or all of the plurality ofcommunication devices 504) is occurring, the detector component 708 canemploy a false positive checker component 718 to determine whether ornot such determination of an aggressive and/or malicious event againstthe RAN 502 is a false positive indication of an aggressive and/ormalicious event against the RAN 502 (as indicated at reference numeral618 of FIG. 6 ).

The false positive checker component 718 can perform additional analysis(e.g., deeper or more detailed analysis) on the information relating thecommunication devices and/or associated messages (e.g., the filteredinformation comprising the relevant information, including informationrelating to communication of control signals), including the respectivecharacteristics associated with the respective communication devices. Inaccordance with various embodiments, the additional analysis performedby the false positive checker component 718 can comprise informationrelating to respective configuration parameters associated withrespective communication devices and/or, when available, respectivedevice reputation information associated with respective communicationdevices, as more fully described herein. Based at least in part on theresults of such analysis, the false positive checker component 718 candetermine whether or not such determination of an aggressive and/ormalicious event against the RAN 502 is a false positive indication of anaggressive and/or malicious event against the RAN 502. In someembodiments, the functions of the false positive checker component 718can be enhanced based at least in part on feedback information (e.g.,false positive checker update information) received from the machinelearning component 706, as more fully described herein. As a result, thefalse positive checker component 718, including its false positivechecking functions, can continue to be improved to enhancedeterminations, by the false positive checker component 718, regardingwhether or not a determination of an aggressive and/or malicious eventagainst the RAN 502 is a false positive indication of an aggressiveand/or malicious event against the RAN 502.

If the false positive checker component 718 determines that thepreliminary determination of an aggressive and/or malicious eventagainst the RAN 502 (e.g., by the detector component 708) is a falsepositive, the false positive checker component 718 can communicateinformation relating to (e.g., indicating) the false positivedetermination to a decision component 720 of the detector component 708(as depicted at reference numeral 620 of FIG. 6 ). The decisioncomponent 720 can determine or decide whether the aggressive and/ormalicious event against the RAN 502 is occurring based at least in parton the information received from the false positive checker component718 (as indicated at reference numeral 622 of FIG. 6 .) Based at leastin part on the information relating to the false positive determination,the decision component 720 can determine that no aggressive and/ormalicious event against the RAN 502 is occurring (as indicated atreference numeral 624 of FIG. 6 ).

As a result, the detector component 708 can communicate informationindicating no aggressive and/or malicious event against the RAN 502 isoccurring to the connection manager component 716. In response toreceiving the information indicating that no aggressive and/or maliciousevent against the RAN 502 is occurring, the connection manager component716 can allow the communication devices to connect to the RAN 502. Atthis point, the SMC 520 can continue to monitor the communicationnetwork, including the RAN 502 and communication devices attempting toconnect to, or already connected to, the RAN 502.

Alternatively, if the false positive checker component 718 determinesthat the preliminary determination of an aggressive and/or maliciousevent against the RAN 502 is not a false positive, the false positivechecker component 718 can communicate information relating to (e.g.,indicating) the non-false positive determination to the decisioncomponent 720 (as depicted at reference numeral 620 of FIG. 6 ). Forinstance, based at least in part on the information relating to thenon-false positive determination, the decision component 720 candetermine that the preliminary determination of an aggressive and/ormalicious event against the RAN 502 occurring is not a false positive,and can determine that there is an aggressive and/or malicious eventagainst the RAN 502 by at least some of the communication devices (e.g.,some or all of the plurality of communication device 504) occurring (asdepicted at reference numeral 626 of FIG. 6 ).

In response to determining that there is an aggressive and/or maliciousevent against the RAN 502 occurring, the decision component 720 cancommunicate information indicating that the aggressive and/or maliciousevent against the RAN 502 is occurring (as depicted at reference numeral626 of FIG. 6 ), wherein the detector component 708 or filter component704 can communicate the filtered information, comprising the relevantinformation, to the connection manager component 716 to enable theconnection manager component 716 to determine whether to block or allowrespective communication devices to connect to the RAN 502, or whetherthe SMC 520 is to perform another type of action besides or in additionto blocking or disconnecting communication devices by or from the RAN502. With regard to the communication devices (e.g., communicationdevice 522, plurality of communication devices 504, or othercommunication devices) attempting to connect to the RAN 502 or alreadyconnected to the RAN 502 during the aggressive and/or malicious event,the SMC 520 (e.g., employing the connection manager component 716) candetermine whether to perform a mitigation action to block or disconnectthe aggressive (e.g., excessive signaling) and/or malicious actingcommunication device(s) (e.g., some or all of the plurality ofcommunication devices 504) or perform another action (e.g., alertaction, log and learn action, or other desired action) to send an alertregarding the aggressive and/or malicious communication device(s), logand learn about the aggressive and/or malicious communication device(s)and associated activity, and/or perform another desired action, based atleast in part on the results of an analysis of the information relatingto the aggressive and/or malicious event (e.g., set of statistics and/orfiltered information) received from the detector component 708 and/orfilter component 704, such as more fully described herein (as depictedat reference numeral 628 of FIG. 6 ).

If a mitigation action to block or disconnect is to be performed, withregard to each communication device (e.g., a device of the plurality ofcommunication devices 504) that is to be blocked from connecting to, orremaining connected to, the RAN 502, the connection manager component716 can generate blocking instructions that can be utilized tofacilitate blocking or discontinuing connection of the communicationdevice to the RAN 502 (as indicated at reference numeral 630 of FIG. 6). The connection manager component 716 can communicate those blockinginstructions to the CU-CP component 512 of the RAN 502 (as indicated atreference numeral 632 of FIG. 6 ). In response to the blockinginstructions, the CU-CP component 512 can block or facilitate blockingthe communication device from connecting to, or remaining connected to,the RAN 502.

Referring again to the machine learning component 706, in addition toenhancing parsing and filtering of information, as disclosed herein, themachine learning component 706 can employ machine learning techniquesand algorithms to learn how to enhance (e.g., improve or optimize)determinations or detections of aggressive and/or malicious eventsagainst the RAN 502 by certain communication devices (e.g.,communication devices infected with malware), enhance determinations offalse positives of preliminary determinations of aggressive and/ormalicious events against the RAN 502, and enhance determining,identifying, or distinguishing between communication devices associatedwith aggressive and/or malicious activity (e.g., excessive signaling)and communication devices associated with benign of acceptable activity.

In some embodiments, the detector component 708, including the falsepositive checker component 718, can communicate the aggressive and/ormalicious event determination and/or false positivedetermination-related information relating to the aggressive and/ormalicious event determinations and/or false positive determinationsand/or the other desired information to the machine learning component706 for analysis (as indicated at reference numerals 634 and 636 of FIG.6 ). The aggressive and/or malicious event determination and/or falsepositive determination-related information can comprise the respectiveinformation (e.g., relevant information) analyzed by the detectorcomponent 708 and/or false positive checker component 718 in connectionwith rendering their respective determinations regarding aggressiveand/or malicious events, information relating to the aggressive and/ormalicious event determination criteria employed by the detectorcomponent 708, and/or information relating to the false positivedetermination criteria employed by the false positive checker component718. The other desired information that can received by the machinelearning component 706 can comprise, for example, the parsing and/orfiltering-related information received from the parser component 702and/or filter component 704, as disclosed herein, and/or other desiredinformation (e.g., the set of statistics and/or information that can berelevant to cell classification or detection of aggressive and/ormalicious activity by communication devices).

The machine learning component 706, employing the machine learningtechniques and algorithms, can perform machine learning analysis on theaggressive and/or malicious event determination and/or false positivedetermination information, the parsing and/or filtering-relatedinformation, historical (e.g., previous) aggressive and/or maliciousevent determination, historical false positive determinationinformation, historical parsing and/or filtering-related information,and/or other desired information (e.g., the set of statistics,information that can be relevant to cell classification or detection ofaggressive and/or malicious activity by communication devices, and/orexternal information received from external data sources). Based atleast in part on the results of such analysis, the machine learningcomponent 706 can determine the aggressive and/or malicious eventdetermination update information that can be used to update the detectorcomponent 708 and/or false positive determination update informationthat can be used to update the false positive checker component 718 toenhance detection or determination of aggressive and/or malicious eventsagainst the RAN 502 and/or determination of whether a preliminarydetermination of an aggressive and/or malicious event against the RAN502 is a false positive or not, respectively, in accordance with thedefined network security criteria.

For example, based at least in part on the results of such analysis, themachine learning component 706, employing the machine learningtechniques and algorithms, can learn how to enhance (e.g., improve oroptimize) detection or determination of aggressive and/or maliciousevents against the RAN 502 and/or determination of whether a preliminarydetermination of an aggressive and/or malicious event against the RAN502 is a false positive or not, in accordance with the defined networksecurity criteria. For instance, the machine learning component 706 canlearn which characteristics or groups of characteristics associated withcommunication devices and/or parameter values of such characteristicscan be more relevant or determinative on the issue of whether there isan aggressive and/or malicious event against the RAN 502 occurringand/or the issue of whether a preliminary determination of an aggressiveand/or malicious event against the RAN 502 is a false positive or not.The machine learning component 706 also can learn respective definedthreshold parameter values associated with respective baselineparameters of respective characteristics associated with communicationdevices that can improve determinations regarding whether an aggressiveand/or malicious event against the RAN 502 is occurring and improvedeterminations regarding whether a preliminary determination of anaggressive and/or malicious event against the RAN 502 is a falsepositive or not.

Based at least in part on such learning, the machine learning component706 can determine the aggressive and/or malicious event determinationupdate information and/or false positive determination updateinformation (e.g., feedback information) relating to such enhancement ofthe detection or determination of aggressive and/or malicious eventsagainst the RAN 502 and/or determination of whether a preliminarydetermination of an aggressive and/or malicious event against the RAN502 is a false positive or not. The aggressive and/or malicious eventdetermination update information can comprise or relate to modificationsthat can be made to the detector functions (e.g., aggressive and/ormalicious event determination functions) of the detector component 708to enhance detection or determination of aggressive and/or maliciousevents against the RAN 502, wherein such modifications can comprise orrelate to modifications (e.g., adjustments, changes, or updates) to thetypes of characteristics or groups of characteristics associated withcommunication devices that are considered relevant or determinative fordetermining whether an aggressive and/or malicious event against the RAN502 is occurring, modifications to respective defined thresholdparameter values associated with respective baseline parameters ofrespective characteristics associated with communication devices and/orother modifications, and/or other modifications to the defined baselineto generate an updated defined baseline. The false positivedetermination update information can comprise or relate to modificationsthat can be made to the false positive determination functions of thefalse positive checker component 718 to enhance determinations regardingwhether a preliminary determination of an aggressive and/or maliciousevent against the RAN 502 is a false positive or not, wherein suchmodifications can comprise or relate to modifications to the types ofcharacteristics or groups of characteristics associated withcommunication devices that are considered relevant or determinative fordetermining whether an aggressive and/or malicious event against the RAN502 is occurring (e.g., determining whether a preliminary determinationof an aggressive and/or malicious event against the RAN 502 is a falsepositive or not), respective threshold parameter values to apply toparameters of respective characteristics associated with communicationdevices, modifications of conditions or events (and associatedcharacteristics associated with communication devices and associatedparameters values) that can be indicative or determinative of whether apreliminary determination of an aggressive and/or malicious eventagainst the RAN 502 is a false positive or not, and/or other types ofmodifications.

The machine learning component 706 can communicate the aggressive and/ormalicious event determination update information to the detectorcomponent 708 (as depicted at reference numeral 638 of FIG. 6 ) and/orthe false positive determination update information to the falsepositive checker component 718 (as indicated at reference numeral 640 ofFIG. 6 ). The SMC 520 (e.g., the detector component 708 or othercomponent of the SMC 520) can modify the detector functions (e.g.,aggressive and/or malicious event determination functions) of thedetector component 708, based at least in part on the aggressive and/ormalicious event determination update information, to enhance thedetection or determination of aggressive and/or malicious events againstthe RAN 502. The SMC 520 (e.g., the false positive checker component 718or other component of the SMC 520) can modify the aggressive and/ormalicious event determination functions of the detector component 708,based at least in part on the false positive determination updateinformation, to enhance determinations regarding whether a preliminarydetermination of an aggressive and/or malicious event against the RAN502 is a false positive or not.

With further regard to the SMC 520 and connection manager component 716,the SMC 520 and/or the connection manager component 716 can communicateinformation relating to aggressive and/or malicious activity bycommunication devices, mitigation action related information,information related to other types of actions, and/or other desired(e.g., pertinent) information to the machine learning component 706 formachine learning analysis (as depicted at reference numeral 642 of FIG.6 ). The machine learning component 706, employing the machine learningtechniques and algorithms, can perform machine learning analysis on theaggressive and/or malicious activity by communication devices,mitigation action related information, information related to othertypes of actions, and/or other desired information, historicalinformation relating thereto, the parsing and/or filtering-relatedinformation, the historical parsing and/or filtering-relatedinformation, the aggressive and/or malicious event determinationinformation, the historical aggressive and/or malicious eventdetermination, the false positive determination information, thehistorical false positive determination information, externalinformation received from external data sources, and/or other desiredinformation. Based at least in part on the results of such analysis, themachine learning component 706 can determine connection managementupdate information that can be used to update the connection managercomponent 716 to enhance determinations regarding whether to blockconnections of communication devices or allow connections ofcommunication devices to the RAN 502 during an aggressive and/ormalicious event against the RAN 502.

For instance, the machine learning component 706 can employ machinelearning techniques and algorithms to learn how to enhance (e.g.,improve or optimize) determinations regarding whether to block or allowconnections of communication devices to the RAN 502 during an aggressiveand/or malicious event against the RAN 502, based at least in part onthe result of the machine learning analysis, in accordance with thedefined network security criteria. For example, the machine learningcomponent 706 can learn modifications that can be made to the definedthreshold priority level that is to be applied when determining whetheraggressive activity (e.g., excessive signaling) associated with acommunication device is sufficiently high (e.g., bad) enough to blockthe aggressive communication device from being connected to the RAN 502(or whether other actions, such as alert action or log and learn actionis to be taken instead) to enhance such connection managementdeterminations and/or modifications that can be made to other connectionmanagement criteria or functions that can enhance the performance ofconnection management functions by the connection manager component 716.

Based at least in part on such learning, the machine learning component706 can determine the connection management update information (e.g.,feedback information) relating to such enhancement of the determinationsregarding whether to block or allow connections of communication devicesto the RAN 502 during an aggressive and/or malicious event against theRAN 502. The machine learning component 706 can communicate theconnection management update information to the connection managercomponent 716 to facilitate updating the connection management functionsof the connection manager component 716 (as indicated at referencenumeral 644 of FIG. 6 ).

The SMC 520 (e.g., the connection manager component 716 or othercomponent of the SMC 520) can modify the connection management functionsof the connection manager component 716, based at least in part on theconnection management update information, to enhance determinationsrelating to whether to perform mitigation actions to block communicationdevices from connecting or remaining connected to the RAN 502,determination of the defined threshold parameter value(s) to apply whenmaking connection management determinations, determinations regardingwhether a parameter value associated with communication devices satisfythe defined threshold parameter value(s), determinations regardingwhether a communication device is to be permitted to connect to the RAN502 (e.g., during an aggressive and/or malicious event against the RAN502), and/or determinations regarding whether a communication device isto be blocked from connecting to the RAN 502 (e.g., during an aggressiveand/or malicious event against the RAN 502).

In certain embodiments, the SMC 520 can include a post-process analyticscomponent 722 that can perform post-process analytics relating toaggressive and/or malicious event determinations, connection managementdeterminations, and/or other operations of the SMC 520, and/or canreceive information relating to post-process analytics performed byanother device or component (e.g., a communication device associatedwith the communication network) to facilitate enhancing performance ofthe SMC 520 with regard to making aggressive and/or malicious eventdeterminations, determining which communication devices can be connectedto the RAN 502 during an aggressive and/or malicious event, and/orotherwise enhancing performance of the SMC 520 (and the RAN 502). Forinstance, the post-process analytics component 722 (or the communicationdevice that communicates the post-process analytics information to thepost-process analytics component 722) can analyze information relatingto aggressive and/or malicious event determinations to determine orfacilitate determining whether a determination by the detector component708 that an aggressive and/or malicious event against the RAN 502occurred was a proper (e.g., correct or accurate) determination,determine or facilitate determining whether the detector component 708failed to detect and classify an aggressive and/or malicious eventagainst the RAN 502 that occurred, determine or facilitate determiningwhether the false positive checker component 718 incorrectly determinedthat an actual aggressive and/or malicious event against the RAN 502 wasa false positive, and/or other desired types of analysis ordeterminations relating to aggressive and/or malicious events. Based atleast in part on the results of such analysis, the post-processanalytics component 722 (or the communication device that communicatesthe post-process analytics information to the post-process analyticscomponent 722) can determine modifications that can be made to thedetector component 708 (or other component(s) of the SMC 520, such asparser component 702 or filter component 704) to enhance (e.g., improveor optimize) determinations (e.g., preliminary determinations and/orfalse positive determinations) relating to malicious events against theRAN 502, and can generate post-process analytics information relating tosuch determination enhancements. The post-process analytics informationcan be utilized to modify the detector component 708 (or othercomponent(s) of the SMC 520, such as parser component 702 or filtercomponent 704) to enhance the performance of the detector component 708(or the other component(s) of the SMC 520).

As another example, the post-process analytics component 722 (or thecommunication device that communicates the post-process analyticsinformation to the post-process analytics component 722) can analyzeinformation relating to connection management determinations todetermine or facilitate determining whether a communication device, suchas a benign acting communication device, was improperly blocked fromconnecting to the RAN 502 or was improperly disconnected from the RAN502 during a mitigation action performed by the SMC 520 during anaggressive and/or malicious event against the RAN 502, or determine orfacilitate determining whether an aggressive and/or malicious actingcommunication device was allowed to connect, or allowed to remain beingconnected, to the RAN 502 during a mitigation action performed by theSMC 520 during an aggressive and/or malicious event against the RAN 502.Based at least in part on the results of such analysis, the post-processanalytics component 722 (or the communication device that communicatesthe post-process analytics information to the post-process analyticscomponent 722) can determine modifications that can be made to theconnection manager component 716 (or other component(s) of the SMC 520,such as parser component 702 or filter component 704) to enhance (e.g.,improve or optimize) determinations relating to managing connections ofcommunication devices during aggressive and/or malicious events againstthe RAN 502, and can generate post-process analytics informationrelating to such determination enhancements. The post-process analyticsinformation can be utilized to modify the connection manager component716 (or other component(s) of the SMC 520, such as parser component 702or filter component 704) to enhance the performance of the connectionmanager component 716 (or the other component(s) of the SMC 520).

In some embodiments, the SMC 520 can comprise an operations managercomponent 724 that can control (e.g., manage) operations associated withthe SMC 520. For example, the operations manager component 724 canfacilitate generating instructions to have components of the SMC 520perform operations, and can communicate respective instructions torespective components (e.g., parser component 702, filter component 704,machine learning component 706, detector component 708, connectionmanager component 716, or other component) of the SMC 520 to facilitateperformance of operations by the respective components of the SMC 520based at least in part on the instructions, in accordance with thedefined communication management or network security criteria, andcommunication management or network security algorithms (e.g., parsingalgorithms, filtering algorithms, machine learning algorithms,aggressive or malicious event detection algorithms, false positivedetermination algorithms, connection management algorithms, or otheralgorithm, as disclosed, defined, recited, or indicated herein by themethods, systems, and techniques described herein).

FIG. 10 illustrates a flow chart of an example method 1000 that canidentify a communication device that is engaging in excessive signalingagainst a RAN of a communication network, in accordance with variousaspects and embodiments of the disclosed subject matter. The method 1000can be employed by, for example, a system comprising the SMC, aprocessor component (e.g., of or associated with the SMC), and/or a datastore (e.g., of or associated with the SMC).

At 1002, a communication device associated with a base station can beidentified based at least in part on communication conditions associatedwith the communication device. The SMC can receive information relatingto communication devices from the communication devices and/or fromnetwork devices associated with the RAN, wherein the communicationdevices can comprise the communication device. With regard to thecommunication device, the information can comprise information relatingto communication conditions (e.g., signal strength, signal quality,timing advance, or other type of communication condition) associatedwith the communication device, information relating to control signals,including, for example, an initial attach request sent by thecommunication device attempting to connect to the RAN, an update attachrequest sent by a communication device that is already connected to theRAN and is requesting some type of update (e.g., updated information orupdated connection), a connection request signal to request a connectionto a base station of the RAN, a handover-related signal associated witha handover of the communication device to or from the base station, orother type of control signal, and/or other desired information relatingto the communication device.

In some embodiments, the SMC (e.g., the detector component of the SMC)can desire to identify a communication device(s), for example, if theSMC has detected unusual activity (e.g., unusually high amount ofcontrol signals sent) by one or more communication devices associatedwith the base station (e.g., detected a total amount of control signalssent by communication devices associated with the base station thatsatisfies a defined threshold total amount of control signals), as morefully described herein. The detector component can utilize informationrelating to communication conditions associated with the communicationdevices to facilitate identifying a communication device(s) that iscausing the unusual activity associated with the base station.

For instance, the detector component can analyze the informationrelating to the communication devices, such as the information relatingto the communication conditions associated with the communicationdevices. Based at least in part on the results of the analysis of suchinformation, the detector component can identify the communicationdevice. For example, the detector component can identify a signature(e.g., communication signature) associated with the communicationdevice, such as one or more communication condition values or ranges ofcommunication condition values (e.g., range of signal strength values,range of signal quality values, or range of timing advance values) thatcan be associated with or representative of the communication devicebased at least in part on the results of analyzing the communicationconditions associated with the communication device (e.g., relative toother communication conditions associated with other communicationdevices associated with the base station). The detector component canidentify the communication device based at least in part on thesignature associated with the communication device.

At 1004, a determination can be made regarding whether to classify thecommunication device as an excessive signaling communication devicebased at least in part on an amount of control signals determined to bereceived from the communication device by the base station and definedcommunication management criteria that can relate to excessivesignaling. The detector component can determine whether to classify thecommunication device as an excessive signaling communication devicebased at least in part on the amount of control signals determined to bereceived from the communication device by the base station and thedefined communication management criteria that can relate to excessivesignaling (e.g., excessive control signaling). For instance, the definedcommunication management criteria can comprise or specify a definedthreshold amount of control signals that can be utilized to indicatewhether a communication device is an excessive signaling communicationdevice. The detector component determine whether the amount of controlsignals determined to be received from the communication device by thebase station satisfies (e.g., meets or exceeds) the defined thresholdamount of control signals.

If the detector component determines that the amount of control signalsassociated with the communication device does not satisfy the definedthreshold amount of control signals, the detector component candetermine that the communication device is not an excessive signalingcommunication device. If, instead, the detector component determinesthat the amount of control signals associated with the communicationdevice does satisfy the defined threshold amount of control signals, thedetector component can determine that the communication device is anexcessive signaling communication device.

If the communication device is determined to be an excessive signalingcommunication device, the SMC can determine a mitigation action that canbe performed to mitigate or facilitate mitigating the excessivesignaling of the communication device, or future excessive signaling ofcommunication devices, and/or can determine a set of statistics (e.g.,an exception level relating to the excessive signaling, trend statisticsrelating to the excessive signaling, statistics relating tocommunication of control signals, a confidence level associated with theexcessive signaling determination or identification of the communicationdevice, or another desired statistic) that can facilitate mitigatingexcessive signaling by communication devices, as more fully describedherein. The SMC (or another component) can perform the mitigation actionto mitigate or facilitate mitigating the excessive signaling of thecommunication device, or future excessive signaling of communicationdevices, and/or can communicate the set of statistics relating to theexcessive signaling to another component or to a user via an interfaceof a device or a messaging account (e.g., email account, text messageaccount, or voice mail account) associated with the user.

FIGS. 11 and 12 depict a flow chart of an example method 1100 that canidentify a communication device that is engaging in excessive signalingagainst a RAN of a communication network and can manage connection ofcommunication devices to the RAN, in accordance with various aspects andembodiments of the disclosed subject matter. The method 1100 can beemployed by, for example, a system comprising the SMC, a processorcomponent (e.g., of or associated with the SMC), and/or a data store(e.g., of or associated with the SMC).

At 1102, signaling by communication devices associated with a basestation can be monitored. The SMC can monitor the communication ofsignals, including control signals, by communication devices to the basestation of a RAN (e.g., to a cell(s) of the base station).

At 1104, a group of signals, including control signals, communicated bythe communication devices to the base station during a defined period oftime can be analyzed. The SMC (e.g., employing the detector component)can analyze the group of signals, including control signals,communicated by the communication devices to the base station during thedefined period of time.

At 1106, a determination can be made regarding whether a total amount ofcontrol signals received from the communication devices during thedefined period of time satisfies a defined threshold total amount ofcontrol signals associated with the base station. The defined thresholdtotal amount of control signals can relate to whether any communicationdevice of the communication devices potentially is an excessivesignaling device in accordance with defined communication managementcriteria. The detector component can classify respective base stationsand/or respective cells of the respective base stations, including thebase station, based at least in part on a result of analyzinginformation relating to respective activity levels of the respectivebase stations and/or respective cells, as more fully described herein.The activity levels of the respective base stations and/or respectivecells can relate, at least in part, to respective amounts of signals,including control signals, that typically are received by the respectivebase stations and/or respective cells during various time periods (e.g.,different times of day, different days of the week, different times of ayear, different times associated with events (e.g., holidays, sportingevents, entertainment events, or other type of events), different timesin relation to events occurring in proximity to a base station or cell,or other types of time periods). For each base station or cell, as partof the classifying, the detector component can determine respectiveamounts of signals that can be considered usual activity of the basestation or cell for respective time periods, and can determinerespective defined threshold total amounts of control signals forrespective time periods associated with a base station or cell, based atleast in part on the respective amounts of signals that can beconsidered usual activity of the base station or cell for the respectivetime periods, in accordance with the defined communication managementcriteria. The respective defined threshold total amounts of controlsignals can comprise the defined threshold total amount of controlsignals associated with the base station for the defined period of time.

The detector component can determine whether the total amount of controlsignals received from the communication devices by the base stationduring the defined period of time satisfies the defined threshold totalamount of control signals associated with the base station andapplicable to the defined period of time based at least in part on theresults of analyzing the signals, including the control signals,communicated by the communication devices to the base station during thedefined period of time.

At 1108, in response to determining that the total amount of controlsignals received from the communication devices by the base stationduring the defined period of time does not satisfy the defined thresholdtotal amount of control signals associated with the base station, adetermination can be made that there is no indication that there is anexcessive signaling communication device associated with the basestation. In response to the detector component determining that thetotal amount of control signals received from the communication devicesby the base station during the defined period of time does not satisfy(e.g., does not breach, or does not meet or exceed) the definedthreshold total amount of control signals associated with the basestation and applicable to that time period, the detector component candetermine that there is no indication that there is an excessivesignaling communication device associated with the base station, atleast at that time. At this point, the method 1100 can proceed toreference numeral 1102 where signaling by the communication devicesassociated with the base station can continue to be monitored, and themethod 1100 can proceed from that point.

If, instead, at reference numeral 1106, it is determined that the totalamount of control signals received from the communication devices by thebase station during the defined period of time satisfies the definedthreshold total amount of control signals associated with the basestation, at 1110, a determination can be made that there is anindication that there at least potentially can be an excessive signalingcommunication device associated with the base station. For instance, inresponse to the detector component determining that the total amount ofcontrol signals received from the communication devices by the basestation during the defined period of time satisfies (e.g., breaches, ormeets or exceeds) the defined threshold total amount of control signalsassociated with the base station, the detector component can determinethat there is an indication that there at least potentially can be anexcessive signaling communication device associated with the basestation.

At 1112, information relating to respective communication conditionsassociated with respective communication devices associated with a basestation can be obtained. The SMC can receive, obtain, or measure therespective communication conditions associated with the respectivecommunication devices associated with the base station.

At 1114, the respective communication conditions associated with therespective communication devices can be determined based at least inpart on the results of analyzing the information relating to therespective communication conditions. The detector component candetermine the respective communication conditions associated with therespective communication devices based at least in part on the resultsof analyzing the information relating to the respective communicationconditions.

At 1116, one or more communication devices can be identified based atleast in part on the respective communication conditions associated withthe respective communication devices. The detector component canidentify (e.g., at least indirectly identify) one or more communicationdevices based at least in part on the results of analyzing therespective communication conditions (e.g., the information relating tothe respective communication conditions) associated with the respectivecommunication devices. For instance, the detector component can identifya first communication device that can have a first set of communicationconditions (e.g., a first communication signature) and/or a secondcommunication device that can have a second set of communicationconditions (e.g., a second communication signature), based at least inpart on the results of analyzing the respective communication conditionsassociated with the respective communication devices, comprising thefirst and second communication devices, wherein the first set ofcommunication conditions can be distinguishable from the second set ofcommunication conditions to enable distinguishing between andidentifying the first communication device and the second communicationdevice. At this point, the method 1100 can proceed to reference point A,as depicted in FIG. 11 , wherein, as depicted in FIG. 12 , the method1100 can proceed from reference point A, as presented in FIG. 12 anddescribed herein.

At 1118, with regard to the one or more communication devices, a numberof control signals communicated by a communication device during thedefined period of time can be determined based at least in part on theresults of analyzing the group of signals received by the base stationduring the defined period of time and the set of communicationconditions associated with the communication device. With regard to eachof the one or more communication devices, the detector component candetermine the number of control signals communicated by thecommunication device during the defined period of time based at least inpart on the results of analyzing the group of signals, including controlsignals, received by the base station during the defined period of timeand the set of communication conditions associated with thecommunication device. For instance, with regard to each of the one ormore communication devices, the detector component can determine anumber of control signals associated with a set of communicationconditions, which can be associated with a communication device tofacilitate identifying the communication device.

At 1120, a determination can be made regarding whether any communicationdevice associated with the base station has communicated a number ofcontrol signals to the base station that satisfies a defined thresholdnumber of control signals based at least in part on the respectivenumbers of control signals communicated to the base station byrespective communication devices during the defined period of time. Withregard to each of the one or more communication devices, the detectorcomponent can determine whether any communication device hascommunicated a number of control signals to the base station during thedefined period of time that satisfies (e.g., breaches, or meets orexceeds) a defined threshold number of control signals based at least inpart on the respective numbers of control signals communicated to thebase station by respective communication devices during the definedperiod of time. The defined threshold number of control signals can bedetermined based at least in part on the defined communicationmanagement criteria. In some embodiments, the defined threshold numberof control signals can be the same with regard to all of thecommunication devices, when doing so is in accordance with the definedcommunication management criteria. In other embodiments, there can bedifferent defined threshold numbers of control signals that can beapplied to different types of communication devices, when doing so is inaccordance with the defined communication management criteria. Forexample, if the detector component has received information that canidentify a type of communication device, and that type of communicationdevice is associated with a particular level or frequency ofcommunication of control signals, there can be a particular definedthreshold number of control signals that can be applicable to that typeof communication device.

At 1122, in response to determining that no communication devicesatisfies the defined threshold number of control signals, it can bedetermined that no communication device is to be classified as anexcessive signaling communication device at this time. If the detectorcomponent determines that no communication device satisfies the definedthreshold number of control signals, the detector component candetermine that no communication device is to be classified as anexcessive signaling communication device at this time. At this point,the method 1100 can proceed to reference point B, as depicted in FIG. 12, wherein, as depicted in FIG. 11 , the method 1100 can proceed fromreference point B to reference numeral 1102 where signaling by thecommunication devices associated with the base station can continue tobe monitored, and the method 1100 can proceed from that point.

Referring again to reference numeral 1120, if, instead, at 1120, it isdetermined that a communication device(s) satisfies the definedthreshold number of control signals, at 1124, the communicationdevice(s) can be classified as an excessive signaling communicationdevice(s). If the detector component determines that the number ofcontrol signals communicated by a communication device(s) to the basestation during the defined period of time satisfies the definedthreshold number of control signals, the detector component candetermine that the communication device(s) can be classified as anexcessive signaling communication device(s).

At 1126, a set of statistics relating to the excessive signaling of theexcessive signaling communication device(s) can be determined based atleast in part on the results of analyzing the information relating tosignaling by the communication devices, including the excessivesignaling communication device(s), associated with the base station,information relating to the base station, and/or the informationrelating to the communication conditions associated with thecommunication devices. The detector component can determine the set ofstatistics (e.g., device identifier information, exception levelstatistics, trend statistics, periodic communication statistics,confidence level statistics, or other desired statistics) relating tothe excessive signaling of the excessive signaling communicationdevice(s) based at least in part on the results of analyzing theinformation relating to signaling by the communication devicesassociated with the base station, information relating to the basestation, and/or the information relating to the communication conditionsassociated with the communication devices, as more fully describedherein.

At 1130, the set of statistics relating to the excessive signaling ofthe excessive signaling communication device(s) can be presented. Thedetector component can present (e.g., communicate, display, or output)the set of statistics relating to the excessive signaling of theexcessive signaling communication device(s) to a communication device,an interface component (e.g., display screen, audio speakers, or otherdesired interface), and/or a user.

Additionally or alternatively (e.g., optionally), at 1132, a mitigationaction, which can be performed to mitigate the excessive signaling ofthe excessive signaling communication device(s), can be determined, inresponse to and based at least in part on the communication device(s)being classified as an excessive signaling communication device(s), forexample, when performing the mitigation action is in accordance with thedefined communication management criteria. In some embodiments, inaddition to, or as an alternative to, determining the set of statistics,the SMC can determine a mitigation action to perform to mitigate (e.g.,reduce or eliminate) the excessive signaling of the excessive signalingcommunication device(s), in response to and based at least in part onthe communication device(s) being classified as an excessive signalingcommunication device(s), for example, when performing the mitigationaction is in accordance with the defined communication managementcriteria. In certain embodiments, the SMC can decide whether toimplement a mitigation action and/or what type of mitigation action toperform to mitigate the excessive signaling of the excessive signalingcommunication device(s) based at least in part on the results ofanalyzing the set of statistics relating to the excessive signaling ofthe excessive signaling communication device(s) and the definedcommunication management criteria, which can comprise the definednetwork security criteria. The types of mitigation action can comprise,for example, blocking communications or attempts to communicate by theexcessive signaling communication device with the base station and/orother base stations, throttling (e.g., partially blocking at least some)communications or attempts to communicate by the excessive signalingcommunication with the base station and/or other base stations,disconnecting or blocking connection of the excessive signalingcommunication device with the base station and/or other base stations,send a message to the excessive signaling communication device torequest or instruct such communication device to reduce the amount ofsignaling and/or change a parameter to reduce the amount of signaling,or another desired type of mitigation action.

At 1134, the mitigation action can be performed to mitigate theexcessive signaling of the excessive signaling communication device(s).The SMC can perform or facilitate performing (e.g., instructing anothercomponent to perform) the mitigation action to mitigate the excessivesignaling of the excessive signaling communication device(s).

In order to provide additional context for various embodiments describedherein, FIG. 13 and the following discussion are intended to provide abrief, general description of a suitable computing environment 1300 inwhich the various embodiments of the embodiments described herein can beimplemented. While the embodiments have been described above in thegeneral context of computer-executable instructions that can run on oneor more computers, those skilled in the art will recognize that theembodiments can be also implemented in combination with other programmodules and/or as a combination of hardware and software.

Generally, program modules include routines, programs, components, datastructures, etc., that perform particular tasks or implement particularabstract data types.

The illustrated embodiments of the embodiments herein can be alsopracticed in distributed computing environments where certain tasks areperformed by remote processing devices that are linked through acommunications network. In a distributed computing environment, programmodules can be located in both local and remote memory storage devices.

Computing devices typically include a variety of media, which caninclude computer-readable storage media, machine-readable storage media,and/or communications media, which two terms are used herein differentlyfrom one another as follows. Computer-readable storage media ormachine-readable storage media can be any available storage media thatcan be accessed by the computer and includes both volatile andnonvolatile media, removable and non-removable media. By way of example,and not limitation, computer-readable storage media or machine-readablestorage media can be implemented in connection with any method ortechnology for storage of information such as computer-readable ormachine-readable instructions, program modules, structured data orunstructured data.

In this regard, the terms“tangible” or “non-transitory” herein as applied to storage, memory orcomputer-readable media, are to be understood to exclude onlypropagating transitory signals per se as modifiers and do not relinquishrights to all standard storage, memory or computer-readable media thatare not only propagating transitory signals per se.

Computer-readable storage media can be accessed by one or more local orremote computing devices, e.g., via access requests, queries or otherdata retrieval protocols, for a variety of operations with respect tothe information stored by the medium.

Communications media typically embody computer-readable instructions,data structures, program modules or other structured or unstructureddata in a data signal such as a modulated data signal, e.g., a carrierwave or other transport mechanism, and includes any information deliveryor transport media. The term “modulated data signal” or signals refersto a signal that has one or more of its characteristics set or changedin such a manner as to encode information in one or more signals. By wayof example, and not limitation, communication media include wired media,such as a wired network or direct-wired connection, and wireless mediasuch as acoustic, RF, infrared and other wireless media.

The system bus 1308couples system components including, but not limited to, the systemmemory 1306 to the processing unit 1304. The processing unit 1304 can beany of various commercially available processors. Dual microprocessorsand other multi-processor architectures can also be employed as theprocessing unit 1304.

The system bus 1308 can be any of several types of bus structure thatcan further interconnect to a memory bus (with or without a memorycontroller), a peripheral bus, and a local bus using any of a variety ofcommercially available bus architectures. The system memory 1306includes ROM 1310 and RAM 1312. A basic input/output system (BIOS) canbe stored in a non-volatile memory such as ROM, erasable programmableread only memory (EPROM), EEPROM, which BIOS contains the basic routinesthat help to transfer information between elements within the computer1302, such as during startup. The RAM 1312 can also include a high-speedRAM such as static RAM for caching data.

The computer 1302 further includes an internal hard disk drive (HDD)1314 (e.g., EIDE, SATA), one or more external storage devices 1316(e.g., a magnetic floppy disk drive (FDD) 1316, a memory stick or flashdrive reader, a memory card reader, etc.) and an optical disk drive 1320(e.g., which can read or write from a CD-ROM disc, a DVD, a BD, etc.).While the internal HDD 1314 is illustrated as located within thecomputer 1302, the internal HDD 1314 can also be configured for externaluse in a suitable chassis (not shown). Additionally, while not shown inenvironment 1300, a solid state drive (SSD) could be used in additionto, or in place of, an HDD 1314. The HDD 1314, external storagedevice(s) 1316 and optical disk drive 1320 can be connected to thesystem bus 1308 by an HDD interface 1324, an external storage interface1326 and an optical drive interface 1328, respectively. The interface1324 for external drive implementations can include at least one or bothof Universal Serial Bus (USB) and Institute of Electrical andElectronics Engineers (IEEE) 1394 interface technologies.

For the computer 1302, the drives andstorage media accommodate the storage of any data in a suitable digitalformat. Although the description of computer-readable storage mediaabove refers to respective types of storage devices, it should beappreciated by those skilled in the art that other types of storagemedia which are readable by a computer, whether presently existing ordeveloped in the future, could also be used in the example operatingenvironment, and further, that any such storage media can containcomputer-executable instructions for performing the methods describedherein.

A number of program modules can be stored in the drives and RAM 1312,including an operating system 1330, one or more application programs1332, other program modules 1334 and program data 1336.

The systems and methods described herein can beimplemented utilizing various commercially available operating systemsor combinations of operating systems.

Computer 1302 can optionally comprise emulation technologies. Forexample, a hypervisor (not shown) or other intermediary can emulate ahardware environment for operating system 1330, and the emulatedhardware can optionally be different from the hardware illustrated inFIG. 13 . In such an embodiment, operating system 1330 can comprise onevirtual machine (VM) of multiple VMs hosted at computer 1302.Furthermore, operating system 1330 can provide runtime environments,such as the Java runtime environment or the .NET framework, forapplications 1332.

Similarly, operating system 1330can support containers, and applications 1332 can be in the form ofcontainers, which are lightweight, standalone, executable packages ofsoftware that include, e.g., code, runtime, system tools, systemlibraries and settings for an application.

Further, computer 1302 can be enable with a security module, such as atrusted processing module (TPM). For instance, with a TPM, bootcomponents hash next in time boot components, and wait for a match ofresults to secured values, before loading a next boot component. Thisprocess can take place at any layer in the code execution stack ofcomputer 1302, e.g., applied at the application execution level or atthe operating system (OS) kernel level, thereby enabling security at anylevel of code execution.

A user can enter commands and information into the computer 1302 throughone or more wired/wireless input devices, e.g., a keyboard 1338, a touchscreen 1340, and a pointing device, such as a mouse 1342. Other inputdevices (not shown) can include a microphone, an infrared (IR) remotecontrol, a radio frequency (RF) remote control, or other remote control,a joystick, a virtual reality controller and/or virtual reality headset,a game pad, a stylus pen, an image input device, e.g., camera(s), agesture sensor input device, a vision movement sensor input device, anemotion or facial detection device, a biometric input device, e.g.,fingerprint or iris scanner, or the like. These and other input devicesare often connected to the processing unit 1304 through an input deviceinterface 1344 that can be coupled to the system bus 1308, but can beconnected by other interfaces, such as a parallel port, an IEEE 1394serial port, a game port, a USB port, an IR interface, a BLUETOOTH™interface, etc.

A monitor 1346 or other type of display device can be also connected tothe system bus 1308 via an interface, such as a video adapter 1348. Inaddition to the monitor 1346, a computer typically includes otherperipheral output devices (not shown), such as speakers, printers, etc.

The computer 1302 can operate in a networked environment using logicalconnections via wired and/or wireless communications to one or moreremote computers, such as a remote computer(s) 1350. The remotecomputer(s) 1350 can be a workstation, a server computer, a router, apersonal computer, portable computer, microprocessor-based entertainmentappliance, a peer device or other common network node, and typicallyincludes many or all of the elements described relative to the computer1302, although, for purposes of brevity, only a memory/storage device1352 is illustrated. The logical connections depicted includewired/wireless connectivity to a local area network (LAN) 1354 and/orlarger networks, e.g., a wide area network (WAN) 1356. Such LAN and WANnetworking environments are commonplace in offices and companies, andfacilitate enterprise-wide computer networks, such as intranets, all ofwhich can connect to a global communications network, e.g., theInternet.

When used in a LAN networking environment, the computer 1302 can beconnected to the local network 1354 through a wired and/or wirelesscommunication network interface or adapter 1358. The adapter 1358 canfacilitate wired or wireless communication to the LAN 1354, which canalso include a wireless access point (AP) disposed thereon forcommunicating with the adapter 1358 in a wireless mode.

When used in a WAN networking environment, the computer 1302 can includea modem 1360 or can be connected to a communications server on the WAN1356 via other means for establishing communications over the WAN 1356,such as by way of the Internet. The modem 1360, which can be internal orexternal and a wired or wireless device, can be connected to the systembus 1308 via the input device interface 1344. In a networkedenvironment, program modules depicted relative to the computer 1302 orportions thereof, can be stored in the remote memory/storage device1352. It will be appreciated that the network connections shown areexample and other means of establishing a communications link betweenthe computers can be used.

When used in either a LAN or WAN networking environment, the computer1302 can access cloud storage systems or other network-based storagesystems in addition to, or in place of, external storage devices 1316 asdescribed above. Generally, a connection between the computer 1302 and acloud storage system can be established over a LAN 1354 or WAN 1356,e.g., by the adapter 1358 or modem 1360, respectively. Upon connectingthe computer 1302 to an associated cloud storage system, the externalstorage interface 1326 can, with the aid of the adapter 1358 and/ormodem 1360, manage storage provided by the cloud storage system as itwould other types of external storage. For instance, the externalstorage interface 1326 can be configured to provide access to cloudstorage sources as if those sources were physically connected to thecomputer 1302.

The computer 1302 can be operable to communicate with any wirelessdevices or entities operatively disposed in wireless communication,e.g., a printer, scanner, desktop and/or portable computer, portabledata assistant, communications satellite, any piece of equipment orlocation associated with a wirelessly detectable tag (e.g., a kiosk,news stand, store shelf, etc.), and telephone. This can include WirelessFidelity (Wi-Fi) and BLUETOOTH™ wireless technologies. Thus, thecommunication can be a predefined structure as with a conventionalnetwork or simply an ad hoc communication between at least two devices.

Wi-Fi, or Wireless Fidelity, allows connection to the Internet from acouch at home, in a hotel room, or a conference room at work, withoutwires. Wi-Fi is a wireless technology similar to that used in a cellphone that enables such devices, e.g., computers, to send and receivedata indoors and out; anywhere within the range of a base station. Wi-Finetworks use radio technologies called IEEE 802.11 (a, b, g, etc.) toprovide secure, reliable, fast wireless connectivity. A Wi-Fi networkcan be used to connect computers to each other, to the Internet, and towired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networksoperate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps(802.11a) or 54 Mbps (802.11b) data rate, for example, or with productsthat contain both bands (dual band), so the networks can providereal-world performance similar to the basic 10BaseT wired Ethernetnetworks used in many offices.
